Intraventricular cavernoma

Intraventricular cavernoma is rare; only 45 cases have been reported in the literature. Magnetic resonance imaging has wildly contributed in the diagnosis and the surgical approach. Case file: We report a 45-year-old man presenting with syndrome of intracranial hypertesion and retrograde amnesia for one year. CT scan and MRI revealed an intraventricular tumour, which was responsible for active hydrocephalus. A ventriculo-peritoneal shunt was performed and a stereotactic biopsy allowed the diagnosis of cavernoma. Post operative follow-up was uneventful, the patient rests asymptomatic. Ventricular cavernoma is rare and should be suspected in atypical localisations in order to chosse the best surgical approach. The author attack the attention to that rare localisation of cavernoma and for its hemorrhagic risles

Exophthalmos as a presenting sign of extradural haematoma

A conscious 14-year old boy admitted to hospital with progressive right exophthalmos, decreased visual acuity and headache 9 days after head trauma, with neurological deficit. Computerized tomography [CT] scan demonstrated intracranial and intraorbital cystic mass. At craniotomy, a subacute extradural haematoma was found which communicated with an orbital subperiosteal haematoma through an orbital roof fracture. Postoperative outcome was marked by complete recovery of exophthalmos and visual acuity. This case demonstrated the rare diagnosis of epidural and subperiosteal orbital haematoma. The literature is reviewed and surgical management is discussed

Lestumeurs de la fosse cereabrale posterieuea [FCP]: [a propos de 150 cas]

The authors have reported the experiment of the neurosurgical department at the "Specialised Hospital" about the tumoral pathology of the posterior cranial fossa concerning 150 cases encountered between 1983 and 1990. In about 56% cases, the patients were young, less than 20. Their clinical aspect was dominated by intracranial hypertension [I.C.H.] syndrome [78%]. Due to the patients delay in consulting, there is blindess in most of the cases [16%]. The CT. scan, carried out systematically in all our patients has amliowed us to distinguish the tumor and to find out an associate hydrocephaly in 62% cases. The main anatomo-pathological types encountered in our series are medulloblastoma in 34 cases, astrocytomas in 30 cases, and neurinoma in 23 cases. The dreadful prognosis of this affection is death in 25% of the cases in the pen-operating period. It is reduced gradually year after year thanks to an early management of the patients, to the progress we have achieved, and to a better multidisciplinary collaboration
