Nonaneurysmal subarachnoid hemorrhage secondary to tuberculous meningitis: report of two cases.

Nontraumatic subarachnoid hemorrhage, one of the life-threatening diseases seen in Emergency Departments, is rarely caused by conditions other than rupture of saccular aneurysms. We report two cases of suspected tuberculous meningitis complicated with nonaneurysmal subarachnoid hemorrhage confirmed by conventional cerebral angiography. Tuberculous meningitis should be considered in the differential diagnoses in cases of nonaneurysmal subarachnoid hemorrhage, especially in tuberculosis endemic areas.
