摘要

黏液瘤(Myxoma)是一個罕見的心臟腫瘤疾病，它也是一個造成腦中風少見的原因，且可能因而造成神經功能永久性的喪失。黏液瘤在各年齡層均可能發生，過去的文獻報告顯示大部份的病例在20-50歲間被診斷出此疾病，其中有一部分患者，即是因為發生了所謂45歲以下的年輕型中風後，才被發現有此一腫瘤。在此我們報告一位44歲男性，以左側肢體無力為缺血性腦中風的初始症狀，經心臟超音波診斷發現有左心房黏液瘤。在經過手術切除腫瘤及復健治療後，其神經功能完全恢復正常。因係少見病例，且早期診治對於病患日後功能的恢復影響很大，希望藉由此病例報告，對心臟黏液瘤之特性，及其造成腦中風之原因，作一討論，並作為臨床醫師日後處理類似疾病時，診斷及治療之參考。

Myxoma is a rare cardiac tumor and also an unusual cause of cerebrovascular accident, which may result in significant permanent neurological deficit. There was no age preference for the development of myxoma. Most of the reported cases in the past were diagnosed between 20 and 50 years of age, and some of them were complicated by young (＜45 y/o) stroke. We presented a 44 y/o man who had ischemic stroke with initial manifestation of left hemiparesis. A cardiac myxoma at left atrium was later detected by transthorasic echocardiography. Total recovery of his neurological dysfunction was achieved after surgical resection of the cardiac myxoma as well as appropriate rehabilitation program. We herein discussed the characteristics of cardiac myxoma and the pathogenesis of the cerebrovascular complication.
