Unusual Multilocular Cardiac Myxomas Presenting with Syncope and Embolic Stroke: A Case Report

大部分的心臟腫瘤是轉移來的，但原發性心臟腫瘤也是重要的致病因，發生率約為千分之三。原發性心臟腫瘤將近半數是黏液瘤，而良性心臟腫瘤中黏液瘤更佔了75%。其他良性心臟腫瘤還包括脂肪瘤，橫紋肌瘤，纖維瘤。本文章描述一年輕女性，一開始未診斷出心臟黏液瘤，後來導致右側偏癱。如果是多房性的心臟黏液瘤，通常會位於兩側心房，該病患則有三個黏液瘤，分別位於兩側心房及左心室。多房性的心臟黏液瘤通常有家族史，並容易復發，該患者則無家族史。經手術切除後，患者臨床症狀完全恢復，追蹤了18個月期間並未復發。

The majority of cardiac tumors are metastatic neoplasms, but primary cardiac tumors are also an important cause of patient morbidity and mortality and occur in 3/1000 of all individuals. About half of primary cardiac tumors and 75% of benign primary cardiac tumors are myxomas. Lipomas, rhabdomyomas, and fibromas make up the majority of the remaining benign tumors. This work describes the clinical course of a symptomatic young female whose multilocular myxomas were not diagnosed initially, who then developed right hemiparesis resulting from cardiac embolization. Myxomas, if multlocular, are mostly biatrial in location. The patient had three myxomas in three chambers of the heart, including both atria and left ventricle, which were identified by transthoracic echocardiography. Multilocular myxomas most often occur in the familial setting, and are often recurrent. The patient's disease was nonfamilial. She received surgical resection successfully, and completely recovered without evidence of recurrence over an 18-month follow-up period.
