OBJECT In this study, the authors report their experience with the surgical treatment of intracranial teratomas with an emphasis on the indications for delayed resection after oncological treatment. METHODS The authors retrospectively reviewed the cases of 14 children with intracranial teratomas. The mean age at diagnosis was 10.5 years (range 2 days-18(More)
Intramedullary cavernous angiomas (ImCA) of the spinal cord are very uncommon malformations especially in the pediatric population where only ten cases have yet been reported within the available literature. In this paper, the authors report the case of a 12-year-old girl presenting with a T11 level hematomyelia because of a cavernous angioma. Microsurgical(More)
A study was made of 75 children treated between 1970 and 1990, with partial, subtotal, or total removal of three intrinsic and 72 exophytic or surface brain-stem tumors. In all cases, the goal of surgery was to remove as much tumor as possible. Extent of removal was defined according to data obtained from postoperative computerized tomography or magnetic(More)
The experience is reported with 50 vertebral fistulas treated by the authors in a joint radiological and surgical team. Of the 28 fistulas that were traumatic, 18 occurred after incidental iatrogenic puncture, and 22 were spontaneous, of which four presented in patients displaying angiographic features of fibromuscular dysplasia. Eleven patients were(More)
OBJECT Craniopharyngiomas are histopathologically defined as benign tumors that can behave very aggressively at the clinical level. They can originate from different types of embryonal epithelial tissue in which correct spatiotemporal regulation has been disrupted at the effector production level. The goal of this study was to determine the efficacy of(More)
INTRODUCTION During the 1970s, frontofacial advancement revolutionized the treatment of severe facial stenosis. Unfortunately, this method was associated with significant morbidity due to the Le Fort III osteotomy, which creates a major communication between the frontocranial dead space and the nasal fossae. Midfacial distraction improves the complication(More)
Juvenile xanthogranuloma (JXG) is one of the most common non-Langerhans cell histiocytosis in children. Usually cutaneous, there are disseminated forms. However, neurological localization remains exceptional. A 7-month-old boy had been admitted for subdural effusion due to non-accidental head injury and skin nodular lesions. A biopsy of a skin lesion was(More)
Traumatic lesions of upper cervical spine are rare in children. To evaluate their experience with this lesions and factors affecting outcome, authors conducted a retrospective study of 28 cases of upper pediatric cervical spine injuries treated in the last 25 years. To help in treatment of these lesions, we studied our series and reviewed the literature.(More)
BACKGROUND Nasal Glial Heterotopias also called Nasal Gliomas (NG) are rare congenital tumours of the midline frontonasal space arising from a normal neurectodermal tissue entrapped during the closure of the anterior neuropore. Historically, such tumours were approached using a frontal craniotomy. The study aims to evaluate a fully endonasal endoscopic(More)
We aimed to assess brain regional glucose uptake (rGlcU) changes in children with isolated cerebellar cortical dysplasia (CCD) using 18-fluoro-deoxy-glucose positron emission tomography (FDG-PET). Six children aged 9 months to 11 years at the time of diagnosis, carrying isolated CCD (with no other associated posterior fossa or supratentorial malformation)(More)
