Management of Tumors of the Cerebellopontine Angle in Developing Countries: Experience of Fann Teaching Hospital in Dakar

Introduction: Cerebellopontine angle (CPA) tumors account for about 5 to 10% of intracranial tumors in the literature. The majority of lesions in this region are benign, so surgery is the main treatment. The literature on the management of these lesions is poor in our context. In this way, we will draw up the epidemiological profile and analyze the diagnostic, therapeutic and evolutionary aspects of this pathology in Dakar. Materials and methods: This is a retrospective study of 51 patients hospitalized in the neurosurgery department of the FANN teaching hospital for the management of the CPA tumors, from January 2007 to December 2018. Results: CPA tumors accounted for 2.8% of intracranial tumors. The average age was 43.4 years and the sex ratio was 0.8. The main signs found were: vestibulo-cochlear syndrome in 66.7% of cases, cerebellar syndrome in 66.7% and HIC syndrome in 56.9% of cases. On imaging, the average size of the tumor was 4.8 cm. The most common tumor was meningioma. Hearing loss and facial paralysis were the most common sequelae. The most common complications are infectious. Conclusion: The tumor pathology of CPA is essentially composed of benign tumors, but of large size in our context making the management of its lesions delicate. Surgery is the main prognostic element found. Keywords: Cerebellopontine angle; Meningioma; Dakar
