Intracranial Meningiomas among Intracranial Tumors in the Neurosurgical Unit of Sylvanus Olympio Teaching Hospital

Objective: To describe the pattern of intracranial tumors in Sylvanus Olympio teaching hospital of Lome (Togo). Method: We conducted a retrospective and descriptive study between November 2017 and December 2019. Data were obtained from the clinical records of patients with intracranial tumors treated in our neurosurgery unit, and histology obtained. Patients without a definitive histological diagnosis were excluded. Results: 53 patients were operated and had a histological diagnosis in the period of the study. The mean age at diagnosis was 32 ± 27.1 years. The majority of tumors were seen in adults at 88.7% with age range between 23 - 75 years and a mean age of 40 ± 10.5 years. Meningioma was the commonest intracranial tumor in adults (47.2%) and more seen in females. The histological type of meningioma is meningotheliomatous in our study. In children, principal tumors were medulloblastoma and ependymoma (11.3%). Conclusion: Meningioma is the most common intracranial tumor in adults, while embryonal tumors (medulloblastoma and ependymoma) are the most frequent in children in our environment.
