Surgical treatment of recurrent torcular meningiomas: case report and review of the literature.

Torcular meningiomas intimately involving major dural sinuses such as superior sagittal sinuses, transverse sinuses, and straight sinuses and the confluence are a great challenge for neurosurgeons. Simpson grade I total resection, which can bring complete cure, is the ultimate goal, but under many circumstances, it is difficult to achieve. The patency of the sinuses around these tumors is the key factor for successful tumor resection, and decides the surgical strategy. We report the experience of complete resection of a huge recurrent torcular meningioma. Related literature is reviewed.
