Abstract
BACKGROUND: Brain tumors of the posterior cerebral fossa (PCF) constitute a serious and frequent pathology that can quickly become life-threatening regardless of age. OBJECTIVE: The aim of this work is to report our experience and results of surgical treatment of FCP tumors in our particular work context. METHODS: We carried out a retrospective study on FCP tumors operated on in the neurosurgery department in Abidjan over a period from JAN 2022 to JAN 2025. All patients operated on for a FCP tumor confirmed by CT scan and/or MRI, regardless of age and sex, were included in the study. Incomplete files were not included in the study. RESULTS: We collected 62 cases of operated FCP tumors with an average age of 28.86 and a sex ratio of 0.72. Patients over 15 years old accounted for 62.9%. Headaches were the reason for consultation in the majority of cases. Intracranial hypertension syndrome (90.3%) and cerebellar syndrome (21.0%) were the most common clinical signs. Ventriculoperitoneal diversion was performed in 98.4% of cases before surgical excision. Tumor excision was performed in all patients. Pilocytic astrocytomas (62.9%) were the most common histological type. The evolution at 1 year was grim with a death rate of 50%. CONCLUSION: Pilocytic astrocytoma is the predominant histological type among FCP tumors. The prognosis remains poor with a high postoperative death rate despite systematic postoperative resuscitation.
