A 65-year-old-man was admitted for evaluation of a transient ischemic attack. A 4.5 x 5.3-cm right atrial mass and a patent foramen ovale were identified by echocardiography. A 0.5-cm lesion was identified in the left temporal lobe of the brain by magnetic resonance imaging. Positron emission tomography was used to differentiate a tumor from an infarct in the brain. The cardiac and the brain lesions were successfully resected. Histopathologic study of the atrial and cerebral tissue demonstrated that these were metastases from a previously excised scalp desmoplastic malignant melanoma. The patient remains well at 14 months' follow-up.
一名65岁男性因短暂性脑缺血发作入院评估。超声心动图检查发现右心房有一个4.5×5.3厘米的肿块以及卵圆孔未闭。磁共振成像在左侧颞叶发现一个0.5厘米的病变。正电子发射断层扫描用于区分脑部肿瘤和梗死灶。心脏和脑部病变均成功切除。对心房和脑组织的组织病理学研究表明，这些是先前切除的头皮促结缔组织增生性恶性黑色素瘤的转移灶。患者在14个月的随访中情况良好。
