A case of neoplastic aneurysm caused by left atrial myxoma is reported. The patient was a 50-year-old woman who has been suffered from occasional vertigo and syncopal attack. She was admitted with a sudden loss of consciousness and cerebellar ataxia on December 1, 1983. Cerebral angiogram revealed multiple aneurysms in the periphery of both middle cerebral arteries and obstruction of the right superior cerebellar artery. Echocardiography displayed a cardiac myxoma in the left atrium. She suddenly died from recurrent cerebral embolism on January 7, 1984. The diagnosis was confirmed by the autopsy. The histopathological examination revealed that the wall of cerebral arteries were destroyed by the tumor cells of myxoma, and it caused cerebral aneurysms. We presented the detail of this case, and discussed about a mechanism and a treatment of neoplastic aneurysms.
报告一例由左心房黏液瘤引起的肿瘤性动脉瘤病例。患者为一名50岁女性，曾偶尔出现眩晕和晕厥发作。1983年12月1日，她因突然意识丧失和小脑共济失调入院。脑血管造影显示双侧大脑中动脉周边有多个动脉瘤，右侧小脑上动脉阻塞。超声心动图显示左心房有心脏黏液瘤。1984年1月7日，她因复发性脑栓塞突然死亡。尸检确诊了诊断。组织病理学检查显示，脑动脉壁被黏液瘤的肿瘤细胞破坏，导致脑动脉瘤。我们介绍了该病例的详细情况，并讨论了肿瘤性动脉瘤的发病机制和治疗方法。
