ABSTRACT: Segmental neurofibromatosis 1 (segmental NF-1) is a rare genodermatosis caused by somatic mutations in the NF-1 gene. It consists of localized characteristic skin lesions. A serial study using magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) of a brain tumor in a 16-year-old patient with segmental NF-1 is reported.
A 16-year-old boy with congenital dorsal scoliosis and segmental NF-1 was evaluated for bilateral optic atrophy. Neurological examination showed an isolated tetra pyramidal syndrome. The cerebral MRI showed a bilateral brain lesion involving the basal ganglia, optic pathways, temporal lobes, and the midbrain. Serial MRSs showed a decreased N-acetylaspartate (NAA)/creatine ratio and increased choline/creatine ratio. An increase in the myoinositol (MYO)/creatine ratio and the presence of a lipid/lactate peak were also recorded. A neuroimaging follow-up with MRI and MRS performed 2 years later showed similar findings.
We describe an MRS study of a brain tumor in a patient with segmental NF-1 for the first time. The MRS study showed similar findings, described earlier in rare studies of patients with the classic form of NF-1. MRS is a noninvasive technique for detecting the presence of tumor tissue in the brain through its metabolic activity. MRS plays an important role in clinical studies and it can be used to differentiate malignant and nonmalignant brain lesions from normal brain tissue.

ABSTRACT: Hypophyseal tuberculoma is extremely rare and difficult to diagnose without a clearly suggestive context. Its radiologic features are not specific and are better recognized on MRI with a mass of a variable signal related to the percentage of caseous necrosis. A frequently associated thickening of the pituitary stalk suggests tuberculosis, requiring the search for another tuberculosis location. This paper reports an original case of hypophyseal tuberculoma since it occurred with no other tubercular infection, which delayed the diagnosis despite thickening of the pituitary stalk on MRI.

ABSTRACT: We report a case of bilateral hearing loss in a child, caused by osteogenesis imperfecta and we evaluate CT scan findings. A 12-year-old child consulted for bilateral hearing loss. A computed tomography scan of the petrous temporal bone showed bilateral extensive unmineralized bone involving the cochleae, vestibules, and semicircular canals extending to the internal auditory canals. Osteogenesis imperfecta of the temporal bone is a genetic connective tissue disorder with increased bone fragility, low bone mass, and other extraskeletal manifestations. Hearing loss is rare in the first 2 decades of life, but it is one of the frequent features of this disorder in adult patients. Thin-section CT scans of the temporal bone show a remarkable proliferation of unmineralized bone involving the otic capsule. This demineralization is similar to that observed in the cochlear form of otospongiosis.

ABSTRACT: To clarify the contribution of the doppler and the CT in the balance aetiology of a fever of the post-partum and to connect it with a thrombophlebitis of ovarian vein.
Five patients presented there post-partum a fever with pointed abdominal painful syndrome. A doppler and a CT were performed.
Doppler showed a hypoechoic tubular structure located forward and laterally with regard to the psoas with a flat spectre in pulsed Doppler in every case. CT confirmed the diagnosis of a thrombophlebitis of the right ovarian vein in three cases and left in two cases. Evolution after anticoagulation and an antibiotic therapy was favourable with regression of clinical signs and doppler evaluation.
In front of any fever of the post-partum, it is necessary to evoke a thrombophlebitis of the vein ovarian, although it is about a rare aetiology. In spite of the superiority of the CT-scan and RP imaging for such a diagnosis, doppler is a simple and reproducible diagnostic tool for the monitoring which must be practised in first intention.

Son aspect radiologique est loin d’être spécifique. Elle se traduit en IRM par un tuberculome de signal variable en fonction de l’importance de la nécrose caséeuse. Souvent, l’association à un épaississement de la tige pituitaire oriente vers une granulomatose hypophysaire et conduit à la recherche d’un foyer tuberculeux. Nous rapportons un cas de tuberculome hypophysaire survenu en l’absence de toute atteinte tuberculeuse concomitante, ce qui a retardé le diagnostic, malgré l’association à un épaississement de la tige pituitaire.

ABSTRACT: PurposeTo evaluate the value of ultrasound and computed tomography in the diagnosis and treatment of primitive psoas abscess in children.Patients and methodsWe retrospectively studied 20 cases of primitive psoas abscess seen between 1987 and 2005. All children were investigated by abdominal ultrasound and computed tomography. Percutaneous drainage of the abscess was performed in 15 cases.ResultsThe mean age of the children was 7.8 years (range: 11 months-12 years). Fever and pain were the presenting symptoms. Ultrasonography established the diagnosis in all patients. CT confirmed the diagnosis and allowed a percutaneous needle aspiration in all cases. Staphylococcus auerus was isolated in 19 patients and streptococcus in 1 patient. The catheter drainage was successful in 14 cases. A surgical drainage was necessary for four children. The two other patients were treated with only antibiotic.ConclusionUS and CT are useful for accurate diagnosis of primitive psoas abscess in children. CT-guided percutaneous drainage is a safe and effective alternative to surgery in the management of primitive psoas abscess.
