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

ABSTRACT

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
