This report presents a case of a 40-year-old woman who was found dead in her house. The examination of the body revealed no external injuries. The whole body was scanned by multi-detector-row computed tomography (CT) before autopsy, revealing massive hemorrhage in the right frontal extending into the ventricular system. At autopsy, the brain parenchyma was removed. Then CT angiography was carried on the isolated brain. Computed tomography angiography suggested a mass of irregular, tortuous vessels in areas of hemorrhage in the right frontal lobe of the brain. Finally, histological examination confirmed the result of CT angiography due to an arteriovenous malformation. Hence, postmortem CT angiography played an important role in diagnosis of the cerebral arteriovenous malformation that was responsible for a massive hemorrhage in the skull.
本报告介绍了一例40岁女性在家中死亡的病例。尸体检查未发现外部损伤。尸检前，通过多排探测器计算机断层扫描（CT）对全身进行扫描，发现右额叶有大量出血并延伸至脑室系统。尸检时，取出脑实质。然后对分离出的大脑进行CT血管造影。计算机断层血管造影显示，在大脑右额叶出血区域有一团不规则、扭曲的血管。最后，组织学检查证实了CT血管造影的结果，病因是动静脉畸形。因此，死后CT血管造影在诊断导致颅骨大量出血的脑动静脉畸形中发挥了重要作用。
