Introduction: The epidemiology, management, and prognosis of cerebral aneurysms in Africa remain poorly understood. Most data to date has been from modeling studies. The authors aimed to describe the landscape of cerebral aneurysms in Africa based on published literature. Methods: Articles on cerebral aneurysms in Africa from inception to June 9, 2020, were pulled from multiple databases (Medline, World Health Organization (WHO) Global Health Library/Global Index Medicus African Journals Online, and Google Scholar). The search results were merged, uploaded into Rayyan. After deduplication, titles and abstracts were screened independently by four reviewers (FDT, USK, IN, NDAB) based on the pre-defined inclusion and exclusion criteria. A full-text review was conducted, followed by data extraction of study, patient, neuroimaging, therapeutic, and prognostic characteristics. Results: Thirty-three articles were included in the full-text retrieval. These studies were published across 13 (24.0%) countries, notably in Morocco (30.3%, n = 10) and South Africa (15.2%, n = 5), and 14 (42.4%) of them were published on or after 2015. Together, the studies totaled 2289 patients; there was a female predominance in 18 (54.5%) study cohorts, and the most frequently cited aneurysms were located in the internal carotid (12.1%, n = 352) and anterior cerebral arteries (9.5%, n = 275). Open surgery (27.3%, n = 792) was the most widely used option in these studies ahead of coiling (3.2%, n = 94). The reported mortality rate following surgical intervention was 7.9%. Conclusion: There are few peer-reviewed reports of aneurysm practice and variability in access to cerebral aneurysm care in Africa.
