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

Background and Importance: Symptomatic vasospasm is a well-known pathology associated with ruptured aneurysms. Nevertheless, this condition is rarely found as a result of skull base tumor removal. Case Presentation: We reported a new case of 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 (SAH). A digital subtraction angiography (DSA) was performed, and a bilateral vasospasm was detected. After subsequent endovascular treatments by intra-arterial infusion of nimodipine, the patient experienced a full recovery. Conclusion: Symptomatic vasospasm after meningioma removal is a challenging and life-threatening condition. Early diagnosis is the key for successful treatment.
