Foramen Magnum Meningiomas: A Report of 10 Cases and Literature Review

AIM: To present the findings and surgical results of foramen magnum meningioma surgeries performed by the authors. MATERIAL and METHODS: Ten patients operated between 2014 and 2019 were retrospectively analyzed in terms of age, gender, neurological examination, and postoperative status. The female-to-male (F/M) ratio of the patients was 6/4, and the age range was 19-70 years (mean = 59). All patients presented with occipitocervical pain and were operated using the midline lateral suboccipital approach. RESULTS: One of the operated patients died in the intensive care unit due to upper gastrointestinal tract bleeding. Additionally, one patient had paresis in the early postoperative period, which resolved in the third follow-up month. CONCLUSION: Foramen magnum meningiomas are operated safely by microsurgical methods using the midline lateral suboccipital approach after suboccipital triangle and vertebral artery are exposed.
