Surgical management of tentorial meningiomas: case series

Abstract

Abstract Background There are several surgical strategies involved in the treatment of patients with tentorial meningioma, and choosing the most appropriate one is not straight forward. Our study aims to illustrate our experience in the management of tentorial meningiomata at our center. Results This study included 32 patients with tentorial meningiomas, operated upon, with assessment of the extent of resection and the Glasgow outcome score (GOS). The mean age at the time of surgery for the studied group was 48.4 years ranging from 20 to 70 years. Total removal was considered as Simpson grade I or II and was achieved in 26 cases (81.25%). Subtotal removal was considered as Simpson grade III or IV and was achieved in 6 cases (18.75%). The final Glasgow outcome score (GOS) for all cases was GOS 1 in 4 cases (12.5%), GOS 4 in 9 cases (28.2%), and GOS 5 in 19 cases (59.3%). Conclusion Tentorial meningiomas can be very challenging during surgery due to their proximity to vital structures. Subtotal resection should be considered when total removal can be hazardous to the patient or result in severe morbidity.
