Severe Edema and Venous Congestion Following Sphenoorbital Meningioma Resection in a Meningiomatosis Case: Importance of Predicting Venous Disturbances

Abstract

To achieve local disease control, radical removal is the best option for sphenoorbital meningiomas. Preservation of the venous system is crucial during the resection of skull base meningiomas. This vascular injury represents a major risk both for life and neurologic function. We present a case of a severe postoperative frontotemporal venous disturbance and cerebral edema following the radical removal of a giant sphenoorbital meningioma in a patient with meningiomatosis and occlusion of the superior sagittal sinus. The anatomical, radiologic, and surgical aspects are reviewed and discussed, with the aim of preventing such a serious complication.
