    ABSTRACT: Background and purpose: Pleomorphic xanthoastrocytomas are rare astrocytic neoplasms of childhood and young adulthood. The purpose of this retrospective review was to evaluate MR imaging features of pediatric pleomorphic xanthoastrocytomas with an emphasis on diffusion MR imaging. Materials and methods: Review of the neuro-oncology data base revealed 11 pediatric patients (range, 4.7-16.1 years) with pleomorphic xanthoastroacytomas with 9 of these patients having preoperative MR imaging available. Six patients had preoperative diffusion MR imaging. Demographics, histopathology slides, conventional imaging characteristics (location, cystic component, hemorrhage, enhancement, vasogenic edema, inner table scalloping), and ADC metrics (mean tumor ADC and tumor to normal brain ADC ratio) were evaluated. Results: Three pleomorphic xanthoastrocytomas had anaplastic features. Ten tumors were supratentorial. Two-thirds (6 of 9) of all tumors were either predominantly cystic or had cystic components, and three-fourths (6 of 8) of the supratentorial tumors had associated inner table scalloping. Seven of the 9 tumors had marked vasogenic edema (>10 mm). Mean tumoral ADC (n = 7) was 912 ± 219 × 10(-6) mm(2)/s (min-max: 617-1189). The tumor to normal brain ADC ratio was 1.14 ± 0.26 (min-max: 0.75-1.47). Conclusions: Pleomorphic xanthoastrocytoma should be entertained in the differential diagnosis of peripheral supratentorial tumors that appear during childhood. Cysts, inner table scalloping, and marked vasogenic edema are relatively frequent features. Relatively low ADC values and ADC ratios are not uncommon in pleomorphic xanthoastrocytoma.

    ABSTRACT: PurposeTo characterize the MRI features of the petromastoid canal in children with sensorineural hearing loss (SNHL) and in normal infants.Materials and Methods High resolution MRI examinations of 564 children who were evaluated for SNHL and brain MRI examinations of 112 infants who had normal studies were studied independently by two reviewers.ResultsIn SNHL group, visibility of the PMC decreased for right and left PMC (P < 0.001). The width of the right PMC significantly decreased as age increased (P < 0.0001). There was no relation between abnormalities of membranous labyrinth and cochlear nerve and PMC visibility in children with SNHL (p > 0.05). In the normal group, the PMC visibility decreased with increasing age (right P = 0.0001, left P = 0.001). In the normal group also, as age increased, the PMC width decreased for both PMCs (right, P = 0.0006; left, P = 0.03).Conclusion The PMC is more frequently visualized in young children. Its visibility and width are not associated with abnormalities of membranous labyrinth and cochlear nerves. J. Magn. Reson. Imaging 2014;39:966–971. © 2013 Wiley Periodicals, Inc.

    ABSTRACT: PURPOSE To test whether apparent diffusion coefficient (ADC) histograms allow for preoperative diagnosis of medulloblatoma subtypes. METHOD AND MATERIALS Retrospective review of Neuro-Oncology database yielded 29 patients (23 male) with medulloblastoma. The pathology specimens were re-evaluated and subcategorized according to the latest WHO classification of the central nervous system tumors. There were 19 classic, 8 desmoplastic/ nodular and 2 large cell medulloblastomas. All patients had preoperative MR imaging performed at a single institution. Diffusion weighted imaging was performed using a spin echo sequence with b=0 and b=1000 s/mm2. ADC maps were generated with a monoexponential fit on a voxel-to-voxel basis for all imaging planes. Internally developed software written in IDL was used for data analysis. T2 weighted and contrast enhanced T1 weighted images were displayed together with ADC map to help visualize the tumor volume. A pediatric neuroradiologist, blinded to the subcategorization, traced the tumor boundaries at as many levels as possible. The ADC histograms for voxels within the ROI were obtained with a bin size of 0.02 x 10-3 mm2/s and normalized by the total number of voxels. The average histogram for each subtype was calculated. Peak height, mean ADC, 10th percentile, 25th percentile, 50th percentile, 75th percentile and 90th percentile points, and skewness were computed. RESULTS The average histogram for each subtype showed significant overlap with other subtypes which did not allow for discrimination. The 10th percentile, 25th percentile, 50th percentile, 75th percentile and 90th percentile points, and skewness were not significantly different among subtypes. CONCLUSION Although utility of ADC histogram analysis was previously shown in preoperative diagnosis of pediatric cerebellar tumors, this method did not prove useful in preoperative discrimination of medulloblastoma subtypes. CLINICAL RELEVANCE/APPLICATION ADC histogram analysis is not useful in preoperative discrimination of medulloblastoma subtypes.

    ABSTRACT: PURPOSE To test the accuracy and applicability of decision rules utilizing ADCratios and age on the accurate preoperative diagnosis of common pediatric cerebellar tumors across institutions. METHOD AND MATERIALS This study was performed at 2 institutions employing different MR scanners. There were 142 pediatric cerebellar tumors. At Site 1, a blinded reviewer placed 3 ROIs on solid components of 98 tumors and normal brain (normal appearing cerebellum and thalamus) on ADC maps. ADCratios were calculated using umoral ADCmean and cerebellar ADC values. ROC analysis was performed to obtain useful thresholds to discriminate pilocytic astrocytomas (PA), ependymomas and embryonal tumors (medulloblastomas and atypical teratoid rhabdoid tumors [ATRT]). Utility of these thresholds were tested using ADCratios obtained from 44 pediatric cerebellar tumors at Site 2 where ADC measurements of the cerebellar tumors and normal brain were performed using the same method employed at Site 1. The utility of age was tested to discriminate medulloblastomas from atypical teratoid/ rhabdoid tumors. RESULTS ADC values of normal brain at Site 1 were significantly different from the ADC values obtained at Site 2. ADCmean of pilocytic astrocytomas were different at Site 1 and Site 2; and ADCmean of embryonal tumors were different at Site and Site 2. The ADCratios were not significantly different for pilocytic astrocytomas, ependymomas and embryonal tumors at Site 1 and Site 2. ADCratio of ≥1.7 was chosen to discriminate pilocytic astrocytomas. 51(91.43%) PAs were correctly diagnosed (32/35 at Site 1; 18/19 at Site 2). ADCratio of <1.2 was chosen to discriminate embryonal tumors. 65 embryonal tumors (97.01%) were correctly categorized (44/45 at Site 1; 21/22 at Site 2). 13(61.90%) ependymomas were correctly diagnosed (11/18 at Site 1; 2/3 at Site 2). Age ≥2.00 years correctly distinguished 48 (84.21%) medulloblastomas (31/37 at Site 1; 17/20 at Site 2) among embryonal tumors. Age <2.00 years correctly discriminated 9 (90.00%) ATRTs (7/8 at Site 1; 2/2 at Site 2) among embryonal tumors. CONCLUSION ADCratios can be reliably used to discriminate common pediatric cerebellar tumors across institutions. Age 2 years is a highly accurate discriminator among embryonal tumors. CLINICAL RELEVANCE/APPLICATION ADCratios can be reliably used to discriminate common pediatric cerebellar tumors across institutions and scanner. Age 2 years is a highly accurate discriminator among embryonal tumors.

    ABSTRACT: Background and purpose: Although utility of diffusion MR imaging in the preoperative diagnosis of common pediatric cerebellar tumors is generally recognized, its added value has not been systematically studied previously. The purpose of this study was to evaluate the impact of diffusion MR imaging on the accuracy of preoperative diagnosis of common pediatric cerebellar tumors among reviewers with different experience levels. Materials and methods: Review of the neuro-oncology data base yielded 96 patients whose preoperative brain MR imaging included both diffusion MR imaging (b = 1000 s/mm(2)) and ADC maps. There were 38 pilocytic astrocytomas, 33 medulloblastomas, 17 ependymomas, and 8 atypical teratoid/rhabdoid tumors. Six reviewers (4 residents, 2 neuroradiologists) evaluated the examinations. Two sessions were conducted with each reviewer, without and with diffusion MR imaging data on 2 separate days. The impact of diffusion MR imaging on accuracy of diagnoses was assessed. Results: In choosing the correct diagnosis of the 4 alternatives, performances of 5 of the 6 reviewers improved significantly with inclusion of the diffusion MR imaging data, from 63%-77% (P = .0003-.0233). The performance of 1 reviewer also improved, but the difference did not attain statistical significance (P = .1944). Inclusion of diffusion MR imaging data improved the likelihood of rendering a correct diagnosis (odds ratio = 3.16, 95% confidence interval = 2.07-4.00) over all tumor types. When embryonal tumors were regarded as a single group, the rate of correct diagnosis increased from 66%-83% with diffusion MR imaging data, and performances of all of the reviewers improved significantly (P = .0001-.05). The improvement in performances resulted from increased correct diagnoses of pilocytic astrocytomas, medulloblastomas, and atypical teratoid/rhabdoid tumors. There was no improvement in the correct diagnoses of ependymomas with inclusion of the diffusion MR imaging data. Conclusions: Diffusion MR imaging improves accuracy of preoperative diagnosis of common pediatric cerebellar tumors significantly among reviewers with differing experience levels.

    ABSTRACT: Purpose. To describe clinical, radiologic, and histological features of a congenital hairy polyp arising from the palatopharyngeus muscle in a neonate. Methods. Chart of a 2-day-old female referred to a tertiary care pediatric hospital for assessment of intraoral mass was reviewed. Results. The child was born at 32 weeks and an intraoral mass was noted. The patient was transferred to tertiary care children's hospital on day 2 of life. The child had increased work of breathing at presentation and required continuous positive airway pressure. Physical examination revealed a pedunculated mass which was protruding into the oropharynx from the nasopharynx. MRI of the lesion documented a discrete bilobed mass which filled the posterior nasopharynx. The mass abutted the uvula and soft palate; however, the mass did not appear to be arising from the soft palate. Intraoperative exam showed a mass arising from the right palatopharyngeus muscle in the superior pole region of the tonsil. Histologic examination showed ectodermal and mesodermal derivatives confirming congenital hairy polyp. At 8-month followup, the surgical site was healed with no evidence of recurrent lesion. Conclusions. Congenital hairy polyp, though uncommon, should be considered in the differential diagnosis of oropharyngeal mass in neonates.

    ABSTRACT: Background: The aim of this study was to assess outcomes of medical and surgical treatment of intratonsillar abscess in children. Methods: The medical charts of children with intratonsillar abscess were reviewed to obtain information on history and physical examination, imaging, management, and follow-up assessment. Results: Eleven children (six male, five female; age range, 4-18 years) were identified. The common complaints included sore throat, fever, and odynophagia. Asymmetric tonsil hypertrophy was present in nine patients and erythema of tonsils in all patients. Peritonsillar fullness was present in three patients. One patient needed emergency intubation due to respiratory compromise. Computed tomography indicated unilateral intratonsillar abscess in nine patients, bilateral intratonsillar abscess in one, and unilateral phlegmon in one. Inflammatory changes were observed in the parapharyngeal space in all patients, retropharyngeal space in one, and pyriform sinus and aryepiglottic folds in two. Antibiotic treatment included clindamycin in seven patients, ampicillin/sulbactam in one, and clindamycin plus ceftriaxone in three. The patients with respiratory compromise underwent surgery prior to antibiotic treatment. Patients with isolated intratonsillar abscess or phlegmon had resolution of their symptoms with i.v. antibiotic treatment. Patients with combination of intratonsillar and peritonsillar abscess required incision and drainage of peritonsillar abscess. Conclusions: Clinically stable children with intratonsillar abscess or phlegmon respond to i.v. antibiotic therapy. Surgical drainage can accomplish clinical resolution in the presence of a combination of intra- and peri-tonsillar abscess, airway compromise, or unresponsiveness to medical treatment.

    ABSTRACT: Although intracerebral schwannomas are typically regarded as benign intracranial tumors, malignancy and recurrence have been reported among patients harboring such neoplasms. The available literature consists of case reports and small series that present variable characteristics distinguishing these unusual lesions. Little advancement has been made to further the understanding and management of these tumors. The authors present 3 cases from their institution that highlight the difference between typical benign intracerebral schwannomas and histopathological variants that may portend more aggressive behavior. Also provided is a review of the literature in the hope of gaining a better understanding of these rare tumors.

    ABSTRACT: Spontaneous perforation of the bile duct (SPBD) is a rare abnormality of the extrahepatic biliary tree in infants. Limited porta hepatis exploration and drainage of the bile-soiled peritoneum are often sufficient treatment. Here, we describe three cases of SPBD, one of which required complex multi-disciplinary interventions for restoration of biliary continuity. Three infants with bilious ascites from spontaneous biliary perforation were reviewed. Metrics included age, presenting symptoms, diagnostic tests, interventions performed, and outcomes. The presenting symptoms of all three infants were bilious ascites, sepsis, lethargy, anorexia, fever and persistent emesis. SPBD was confirmed pre-operatively by HIDA scan (hepatobiliary scintigraphy) in each case. Intra-operative, trans-cholecystic cholangiogram confirmed SBDP in two cases. Two of the infants were successfully treated with placement of a cholecystostomy tube and porta hepatis drains. The third infant, having failed multiple similar drainage procedures, required percutaneous transhepatic drainage of a persistent porta hepatis biloma. Ultimately percutaneous, transhepatic cannulation of the extra-hepatic biliary tree for prolonged stenting was required to successfully treat this biliary perforation. Complex spontaneous biliary perforation may require extensive interventions if the perforation fails to resolve with standard porta hepatis drainage. Access of the biliary tree via Interventional Radiology procedures for complex biliary disease of this type is novel and presents an alternative to traditional open surgical treatment and control of spontaneous biliary perforations.

    ABSTRACT: We describe the diagnosis and management of a child with embryonal rhabdomyosarcoma of the auricle and emphasize both clinical and radiological findings of this rare condition. A nine-year-old boy presented for evaluation of a slowly enlarging left auricle mass. The mass was nodular, violaceous, semi-translucent, and hyperpigmented with an overlying pseudo-vesicular plaque. The mass appeared to involve the left cavum concha, root of the helix, superior aspect of the external auditory canal, the tragus and extend to a deep preauricular component. MR imaging documented a lobulated soft tissue mass surrounding the external auditory canal with superficial involvement of the pinna. Incisional biopsy of the mass suggested embryonal rhabdomyosarcoma. The tumor was completely removed by total auriculectomy and lateral temporal bone resection. The final diagnosis was embryonal habdomyosarcoma. Although rare, otolaryngologists, pediatricians, and radiologists need to consider rhabdomyosarcoma in the differential diagnosis of auricle mass in children.

    ABSTRACT: PURPOSE To identify the specific sites of the spinal drop metastases in children with brain tumors in pursuit of improved scanning strategies. METHOD AND MATERIALS Retrospective review of institutional neuro-oncology database from January 2000 through September 2011 yielded 191 children who had pathology proven brain tumors and underwent preoperative spine MRI for evaluation of drop metastases at our institution. All studies were performed following administration of intravenous gadolinium. The anonymized studies were presented to a board certified radiologist with certificate of additional qualification in neuroradiology and were evaluated with respect to the presence and absence of drop metastases. When drop metastases were present, 5 specific sites (cervical spinal cord, thoracic spinal cord, conus medullaris, cauda equina, and terminus of the thecal sac) were assessed individually. RESULTS There were 32 patients (21 male) with spinal drop metastases. Twenty-five patients underwent imaging at 1.5 Tesla and 7 at 3.0 Tesla. The tumors with spinal drop metastases comprised of 16 medulloblastomas, 5 pilocytic astrocytomas, 4 atypical teratoid/rhabdoid tumors, 4 pineal tumors (pineoblastoma and germinoma), and 3 ependymomas. Thirty (93.8%) of the 32 patients had drop metastases involving the conus medullaris, cauda equina or terminus of the thecal sac. There were 2 patients who had drop metastases in the upper segments (cervical and thoracic) of the thecal sac, but not in lower segments (conus medullaris, cauda equina, and terminus of the thecal sac). Among those patients (n=18) who had drop metastases in the upper segments, only 1 did not did not have disease in the lower segments. The conditional probability of having disease in lower segments when disease is present in upper segments was P=94.4%. CONCLUSION Drop metastases are more likely to involve the lower segments of the thecal sac in children with brain tumor. CLINICAL RELEVANCE/APPLICATION MR scanner time, a limited resource, may be better utilized with dedicated high resolution imaging of the lower segments of the spine in addition to screening of the cervical and thoracic spine

    ABSTRACT: We hypothesized that the silent cerebral infarcts (SCI), which affect up to 40% of children with sickle cell disease (SCD), could occur in the setting of acute anemic events. We conducted a prospective observational study of children with and without SCD hospitalized for an illness associated with acute anemia. We identified acute silent cerebral ischemic events (ASCIE) in 4/22 (18.2%) with SCD and in 2/30 (6.7%) without SCD, using diffusion-weighted magnetic resonance imaging (DWI). Children with ASCIE had lower hemoglobin concentration than those without (median 3.1 vs 4.4 g/dl, p=0.003). The unique temporal features of cerebral infarction on DWI permit estimation of incidence rates for ASCIE of 421 (95% C.I. 155-920) per 100 patient years during acute anemic events for all patients. For children with SCD, the estimated incidence was 663 (95% C.I. 182-1707) which is much higher than reported in longitudinal studies of silent or overt strokes in SCD. Acute anemic events are common in children with SCD and therefore could partially account for the high SCI prevalence. Some ASCIE (1/4 in our study) may be reversible. Alterations in management may be warranted for all children with severe anemia to identify unrecognized ischemic brain injury that may have permanent neurocognitive sequelae.

    ABSTRACT: Objective: To describe clinical, radiologic, and histological features of a foregut duplication cyst extending from the oropharynx to the thoracic inlet. Methods: The medical record of one-month-old female who was referred to a tertiary care pediatric hospital for assessment of a neck mass was reviewed. Data included relevant history and physical examination, diagnostic work up, and management. Results: The child presented with a left neck mass identified during prenatal ultrasound exam. The infant gradually developed choking, gagging, and noisy breathing with feeds. Physical examination revealed a neck mass, extending from left submandibular region to left clavicle, was well-marginated, painless, soft, immobile, and nonadherent to the skin. A computerized tomography of the neck demonstrated a unilocular cystic mass extending from the level of the posterior oropharyngeal airway to the thoracic inlet. The mass was excised and histopathologic diagnosis was foregut duplication cyst. Conclusion: Foregut duplication cyst, although uncommon in the neck region, should be considered in the differential diagnosis of neck mass in children.

    ABSTRACT: A technique to retrieve double J stents was described in children in whom cystoscopic stent removal was not feasible. In three children, the caudal ends of the double J stents were retrieved via the percutaneous nephrostomy access. Capturing the caudal end of the double J stents for retrieval made removal feasible and easy.

    ABSTRACT: Juvenile xanthogranulomas (JXG) are uncommon non-Langerhans cell histiocytic proliferations which arise most often in children. While most cases present as solitary cutaneous lesions, occasional cases involve extracutaneous sites. Rare examples of JXGs have been reported involving all levels of the neuroaxis. We present two cases of JXGs involving the nervous system, and review the literature. The first patient was a 14-year-old female with headaches and a mass involving the left trigeminal nerve; pathologic examination showed a JXG. At 11 months follow-up, after administration of systemic chemotherapy, the patient remained stable with residual tumor. The second patient was a 15-year-old female with leg weakness and numbness, who underwent complete surgical resection of a dural JXG. At eight months follow-up, she showed no evidence of tumor, and was able to walk without difficulty. Review of the literature revealed 38 previously published reports of JXGs involving the nervous system. The CNS was involved in the majority (75%) of cases. The clinical characteristics of JXGs arising in the CNS varied significantly from cases in the peripheral nervous system (PNS); CNS tumors occurred in younger patients, more often males, and were more likely to be associated with concurrent cutaneous and extra-nervous systemic lesions. The clinical outcomes were similar for CNS and PNS lesions, with the caveat that all three lethal JXGs occurred in the CNS. The clinical and radiologic presentation of JXGs is nonspecific, thus necessitating biopsy and pathologic examination to arrive at the diagnosis. The pathologic differential diagnosis includes a heterogeneous group of histiocytic proliferations; immunostaining for histiocytic markers CD68, factor XIIIa, and Fascin, and the absence of Birbeck granules and CD1a immunoexpression suggests the diagnosis of JXG. In many cases, total surgical resection is curative. However, some cases will require additional chemotherapy and/or radiotherapy.

    ABSTRACT: The aim of this study was to identify clinically useful tumor/normal brain apparent diffusion coefficient (ADC) ratios for distinguishing common pediatric cerebellar tumors. Review of medical records revealed 79 patients with cerebellar tumors who underwent preoperative magnetic resonance imaging, including diffusion-weighted imaging sequences, and surgery. There were 31 pilocytic astrocytomas, 27 medulloblastomas, 14 ependymomas, and seven atypical teratoid/rhabdoid tumors. ADC values were measured by placing regions of interest on the solid tumor and normal brain parenchyma by two reviewers. Tumor/normal brain ADC ratios were calculated. Mean ADC values of the pilocytic astrocytomas were greater than those of ependymomas, whose mean ADC values were greater than those of medulloblastomas and atypical teratoid/rhabdoid tumors. Using a tumor/normal brain ADC ratio threshold of 1.70 to distinguish pilocytic astrocytomas from ependymomas, sensitivity of 92% and specificity of 79% were achieved. A tumor/normal brain ADC ratio threshold of 1.20 enabled the sorting of ependymomas from medulloblastomas with sensitivity of 93% and specificity of 88%. Tumor/normal brain ADC ratios allow the distinguishing of common pediatric cerebellar tumors.
