Delayed Bilateral Symptomatic Vasospasm after Resection of a Skull Base Meningioma: Report on a New Case and Literature Review

Background & Importance: Symptomatic vasospasm is a well-known pathology associated with ruptured aneurysms. Nevertheless this condition could be rarely found as a result of skull base tumor removal.
We reported on a new case of a 40 year old woman previously treated for a tuberculum and diaphragma sellae meningioma showing symptomatic vasospasm after twelve post-operative days without previously documented sub-arachnoid hemorrhage. A digital subtraction angiography (DSA) was performed, and a bilateral vasospasm was detected. After subsequent endovascular treatments by intra-arterial infusion of nimodipine, patient experienced a full recovery.
Symptomatic vasospasm after meningioma removal is a challenging and life-threatening condition. Early diagnosis is
the key for successful treatment.
