[Hemangiopericytoma of the lumbar spine]. / Hemangiopericytome vertebral lombaire.

Hemangiocytoma are rare malignant vascular tumor. Vertebral location is uncommun. They occur preferentially at the lumbo-sacrul spine with paravertebral extension. The features include spinal pains, para vertebral tumefaction and paresthesia. The CT and MRI scans can help to diagnosis which is histological. The treatment is surgical combined or no with radiotherapy. The pronostic is marqued by the recidive risk and metastases. We report a new case of vertebral hemangiopericytoma of the thoraco-lumbar spine with litteratur review.

[Intradiploic hematoma: report of two cases and review of literature]. / L'hématome intradiploïque. Deux nouveaux cas et revue de la littérature.

Diploic hematoma is an uncommon lesion which develops generally after minor head trauma. Only seven cases have been published so far and we are reporting two new cases of diploic hematoma in infancy. The diagnosis was made by computerized tomography and confirmed by histology. Diploic hematoma should be considered as part of the differential diagnosis in case of with a diploic lesion.

[Cerebellar liponeurocytoma. Case report]. / Le liponeurocytome cerebelleux: a propos d'une observation.

The cerebellar liponeurocytoma is a rarely and recently described tumour. It may be distinguished on the basis of neuroimaging findings that demonstrate the areas of fat density. Complete surgical removal with postoperative radiation therapy is recommended. It has a relatively more favourable prognosis. We report the case of a 38-year-old woman without particular pathological antecedent with a few months history of headache and dizziness, aggravated since 2 days by signs of increased intracranial pressure and cerebellar dysfunction. The Computerized Tomography practiced in emergency showed a subtentorial space occupying mass, heterogeneous, exhibiting the attenuation values of fatty tissue, with hydrocephalus upstream. The patient has been operated. The histopathological and immunohistochemical studies concluded to a cerebellar liponeurocytoma.

[Imaging diagnosis of an unilateral painful ophtalmoplegia]. / Diagnostic radiologique d'une ophtalmoplegie douloureuse unilaterale.

The ophtalmoplegia may be due to several lesions and the diagnosis is made by imaging modalities. We report the case of a giant aneurysm of the wright intracavernous internal carotid artery revealed by painful ophtalmoplegia with subarachnoid haemorrhage. The diagnosis was made by magnetic resonance imaging and angiography.

[Radiation-induced intracerebral cavernous angioma]. / Le cavernome cérébral radio-induit. A propos d'un cas.

Recently, there have been several case reports of cavernous angiomas appearing after radiation to the brain, typically in children. The time interval between irradiation and the detection of the cavernous angioma varied from three to nine years and the doses from 24 to 60 grays. We report the appearance of a cavernous malformation in a young girl 3 years after radiation therapy for a brain tumor.
