Atypical radiological and intraoperative findings of acute cerebral hemorrhage caused by ruptured cerebral aneurysm in a patient with severe chronic anemia.

Atypical radiological and intraoperative findings of acute cerebral hemorrhage caused by ruptured cerebral aneurysm in a patient with severe chronic anemia. J Nippon Med Sch. 2014;81(4):264-8 Authors: Matano F, Murai Y, Nakagawa S, Kato T, Kitamura T, Sekine T, Takagi R, Teramoto A Abstract Acute intracerebral hemorrhage (ICH) associated with mild anemia is commonly observed on radiological examination, and there are several reports of ruptured aneurysms occurring with ICH but without accompanying subarachnoid hemorrhage. However, the relationship among computed tomography (CT), magnetic resonance imaging (MRI), and intraoperative findings of ICH caused by ruptured cerebral aneurysm in patients with severe chronic anemia has been rarely reported and is poorly understood. Here, we report atypical radiological and intraoperative findings of acute ICH caused by ruptured cerebral aneurysm in a patient with severe chronic anemia. A 64-year-old man with anemia was admitted to our hospital after he experienced left hemiparesis and a disturbance of consciousness. At a referring institution, he showed evidence of macrocytic anemia (white blood cell count, 9,000/μL; red blood cell count, 104×10(4)/μL; hemoglobin, 4.0 g/dL; hematocrit, 12.2%; and platelet count, 26.6×10(4)/μL). Both CT and MRI showed a right frontal ICH. The outer ring of the hematoma appeared as low-density area on CT, a low-intensity area on T1-weighted MRI, and a high-i...
