The association of a meningioma and intratumoral aneurysm is extremely rare. The coexistence of both lesions may cause difficulties in diagnosis and treatment. We present the case of a 65 y.o. woman with a left temporal meningioma and an intralesional ruptured aneurysm of a terminal branch of the middle cerebral artery whose parental vessel fed the tumor. The tumor and the embedded aneurysm were removed safely with improvement of her symptoms.
