ABSTRACT: Infantile fibrosarcoma represents less than 1% of all childhood cancers, but it is the most common soft-tissue sarcoma in those under 1 year of age. We report an infant with congenital infantile fibrosarcoma diagnosed as hemangiopericytoma. He was treated with chemotherapy and extremity-sparing surgery. Amputation was avoided.

ABSTRACT: Here, we review the CT and MR angiography findings of aberrant right subclavian and right vertebral arteries, with emphasis on the differences between these structures. In addition, non-invasive imaging findings of aberrant right subclavian artery pathologies, including arteritis, aneurysm and dissection, are discussed.

ABSTRACT: Growth factors have been implicated in the pathogenesis of autism. We have investigated daily urinary excretion of insulin-like growth factor-1 (IGF-1), epidermal growth factor, and insulin-like growth factor binding protein-3 in autistic children (n=34, age 2-5 years) and age-matched control children (n=29). The mean urinary IGF-1 level was lower in the autism group than the control group (p=0.03). Height was normal. These findings suggest altered IGF-1 metabolism in young autistic children. The cause-effect relationship should be examined by longitudinal studies and insulin-like growth factor provocation tests.

ABSTRACT: Multidetector row CT (MDCT) is a non-invasive and rapid technique used for the evaluation of paediatric vascular diseases as an alternative to conventional angiography. Three-dimensional (3D) images allow excellent display of vascular anomalies that can be used as a vascular road map by surgeons. The aim of this pictorial review is to demonstrate diagnostic MDCT angiographic findings of various congenital thoracic vascular anomalies in paediatric patients. It is important to recognize these anomalies early for proper treatment and follow-up, and also to prevent morbidities and mortalities.

ABSTRACT: A pseudoaneurysm is defined as an aneurysmatic sac surrounded byfibrous tissue instead of other vascular layers such as the muscular one. It is a rare incident in infants especially in the brachial artery. Blunt trauma and vascular access attempts are the most common etiologic factors. We present two infants with brachial artery pseudoaneurysm in the antecubital region following accidental arterial puncture.

ABSTRACT: Congenital mesoblastic nephroma is the most common renal mass in the newborn period and can present with atypical findings. Certain associated conditions such as hypercalcaemia, hypertension and reninism have been described. We report a cellular variant of congenital mesoblastic nephroma with hypercalcaemia and contralateral medullary nephrocalcinosis.

ABSTRACT: Inflammatory myofibroblastic tumour is a rare entity in children with few reported series. The extrahepatic bile duct is an unusual location for this tumour. The authors report here the case of an 8-year-old girl presenting with obstructive jaundice due to inflammatory myofibroblastic tumour of the extrahepatic bile ducts with differential diagnosis of obstructive jaundice in children.

ABSTRACT: A 7-month-old patient with Wiskott-Aldrich syndrome (WAS) developed pneumatosis intestinalis (PI) in the immediate post-transplant period after receiving paternal human leucocyte antigen (HLA) phenotypically matched bone marrow (BM). PI has been described in patients with congenital or acquired immunodeficiency states and after bone marrow transplantation (BMT). To our knowledge, the condition has not been described in WAS. The underlying bowel mucosa damage as a result of the history of massive rectal bleeding, the effects of the conditioning regimen, immunosuppression, neutropenia, and infection, may all have contributed to the development of PI. Although the condition resolved by conservative management alone, the patient developed Klebsiella pneumonia sepsis, interstitial pneumonitis, failed to engraft, and died on day +66 following a second infusion of stem cells mobilized from his father's peripheral blood.

ABSTRACT: Langerhans cell histiocytosis (LCH) is a disease of unknown cause characterised by proliferation of histiocytic granulomas in tissues; the primary cerebral manifestation is diabetes insipidus caused by hypothalamic infiltration. We present a patient in whom, except for the absence of high signal on T1 weighting in the posterior pituitary, consistent with central diabetes insipidus, MRI showed no evidence of hypothalamic involvement by histiocytosis, despite the long duration of the disease. However, there was bilateral, symmetrical involvement of the cerebellum and globus pallidus in addition to a calvarial lesion. High signal in the cerebellar white matter on T2-weighted images may represent demyelination, gliosis and cell loss, as previously reported on pathologic examination.

ABSTRACT: The purpose of this study was to determine the diagnostic value of diuretic duplex Doppler sonography in distinguishing between obstructive and nonobstructive hydronephrosis in children by calculating the resistive indices (RI) before and after administration of furosemide.
We prospectively evaluated 28 kidneys (2 solitary) in 15 patients with unilateral or bilateral neonatal hydronephrosis. All patients underwent diuretic renography and duplex Doppler sonography before and after administration of furosemide.
According to the half-time drainage patterns at diuretic renography, 13 kidneys were classified as nonobstructed and 15 as obstructed. At baseline, the mean RI values of nonobstructed and obstructed kidneys were not significantly different (0.66 and 0.64, respectively). Ten minutes after the injection of furosemide, the mean RI values of the nonobstructed and obstructed kidneys were 0.68 and 0.70, respectively. The increase in RI over the baseline 10 min after the diuretic injection was statistically significant (p<0.00001) in the obstructed kidneys.
The baseline RI value of 0.70 is not a definite value for distinguishing obstructed from nonobstructed systems. An increase in RI of at least 10% over the baseline seems to be a more reliable criterion, especially when it is used in conjunction with diuretic renography.

ABSTRACT: A 14-year-old girl with Robinow syndrome was admitted with severe abdominal pain that had recurred periodically during the last 6 months. She had been followed by us since age 2 months and she had not experienced menarche yet; hematocolpos related to vaginal atresia was diagnosed. She underwent vaginoplasty with cervical construction. Genital system abnormalities are common in Robinow syndrome, but this kind of malformation has not been reported previously.
