This report describes a 52-year-old black male with the isolated finding of an anomalous superior vena cava draining into the left atrium. The patient presented with dizziness, mild cyanosis, polycythemia and normal cardiac and pulmonary findings. The first major diagnostic clue in this confusing clinical presentation was an unsuccessful lung perfusion scan in which intravenous tracer consistently bypassed the lungs. This appears to be the first adult presenting with this rare anomaly. This condition should be suspected if cyanosis, clubbing, and a "normal" cardiac examination coexist and if the more common pulmonary and hematological causes of this triad have been excluded.
本报告描述了一名52岁的黑人男性，其单独发现异常的上腔静脉引流至左心房。患者表现为头晕、轻度发绀、红细胞增多症，心脏和肺部检查结果正常。在这种令人困惑的临床表现中，第一个主要诊断线索是肺灌注扫描未成功，静脉注射示踪剂始终绕过肺部。这似乎是首例出现这种罕见异常的成人病例。如果发绀、杵状指和“正常”心脏检查同时存在，且已排除导致这三联征的更常见的肺部和血液学原因，则应怀疑这种情况。
