A case of surgically proven left atrial myxoma presented with multiple episodes of cerebral infarctions, both ischemic and hemorrhagic, documented on serial CT and magnetic resonance (MR). Magnetic resonance studies showed, as well, dilated blood vessels in the hemorrhagic areas, proven by angiography to represent mycotic aneurysms. One of these lesions was surgically removed and confirmed to represent a combination of hematoma, infarction, myxomatous nodules, and underlying mycotic aneurysms, as shown on MR scans. This case demonstrates a known delayed neurologic complication of cardiac myxoma that can occur long after resection of the tumor.
一例经手术证实的左心房黏液瘤患者出现多次脑梗死发作，包括缺血性和出血性梗死，连续CT和磁共振成像（MR）均有记录。磁共振研究还显示，出血区域有血管扩张，血管造影证实为真菌性动脉瘤。其中一个病变经手术切除，病理证实为血肿、梗死、黏液瘤结节及潜在真菌性动脉瘤的组合，如MR扫描所示。该病例显示了心脏黏液瘤一种已知的延迟性神经并发症，可在肿瘤切除后很长时间发生。
