Objective: We present our experience in managing foramen magnum meningiomas (FMM) and discuss various surgical approaches and outcome

Methods: We reviewed 14 consecutive cases of FMM operated between October 2006 and December 2013.

Results: There were 11 female and 3 male patients (mean age: 62.5 years). Gait disturbances were the most common cause of presentation and was present in 65% of cases. Lateral and midline approaches were performed in 10 and 4 cases, respectively. Total resection was achieved in 85% of cases. With a mean follow up of 36 Months no recurrence or remnant growth was seen. Main complications were transient lower cranial nerve deficits in 5 cases (35%), cerebrospinal fluid fistula and lung embolism in one case (7%) each.

Conclusion: FM meningiomas can be safely resected with excellent oncological and clinical outcome either with a posterior midline suboccipital or far-lateral approaches with minimal condylar drilling.
