Abstract
BACKGROUND: Although meningiomas are considered benign, encapsulated brain tumors, their distinct intracranial location can lead to devastating complications. Although a highly vascularized tumor, a rarely reported complication of meningioma is hemorrhage. To the best of our knowledge, only 19 cases of meningioma presenting with a subdural hematoma have been reported. CASE DESCRIPTION: We have outlined the clinical presentation, radiological findings, and outcomes of 2 female patients with a diagnosis of a spontaneous subdural hematoma associated with meningioma. The coagulation profile was within normal limits for both patients. The postoperative histopathologic examination results showed an angiomatous/microcystic subtype of meningioma (patient 1) and meningothelial meningioma (patient 2). Both patients underwent right frontal craniotomy, resection of the dural-based tumor, and evacuation of the subdural hematoma. CONCLUSIONS: We comprehensively reviewed the pertinent data for meningiomas presenting as subdural hematomas. The mechanism of hemorrhage in meningiomas remains unclear. Therefore, further studies are required to investigate the possible mechanisms of bleeding in such tumors.
