Three Cases of Intracranial Hematoma Associated with Meningioma

ABSTRACT

Spontaneous intracranial hematoma in patients with brain tumors is well recognized, However, intracranial hematoma associated with meningioma has been rarely reported. Not infrequently, clinical manifestations of such tumors have been masked by the associated hematoma, which preclude correct diagnosis of these tumors. Meningioma-associated hemorrhages have been reported regardless of sex, age, or location and histology of the tumor. The mechanisms of such hemorrhage are yet to be clarified. During the last two years, we have experienced three cases of intracranial hemorrhage associated with meningioma. Two of them occurred acutely without antecedent symptoms of the meningioma and other one after gamma knife surgery of meningioma. We reviewed partinent literature and discussed possible mechanisms of these rare intratumoral or peritumoral hemorrhages associated with meningiomas.
