title: Meningioma manifesting as cerebral infarction.
abstract: A previously healthy 31-year-old man presented with an extremely rare case of small meningioma associated with cerebral infarction preceded by recurrent transient ischemic attacks manifesting as a 3-day history of recurrent and transient weakness of the left lower limb lasting several minutes for each episode. The symptoms became persistent and complete on the following day. Magnetic resonance imaging revealed acute cerebral infarction in the right frontal lobe and a 20 mm diameter tumor in the planum sphenoidale encasing the right anterior cerebral artery. Cerebral angiography demonstrated occlusion of the right A(2) portion. The patient underwent surgery and the tumor was gross totally removed. The histological diagnosis was meningothelial meningioma. Cases of meningioma causing cerebral infarction are very rare, but the possibility should be considered even if the tumor is small.
