Catecholamine-induced cardiomyopathy associated with pheochromocytoma is a well-recognized but rare entity. Both hypertrophic and dilated variants have been described. We report a case of dilated cardiomyopathy associated with a benign pheochromocytoma that showed complete normalization of left ventricular systolic function following removal of the tumor. Serum noradrenaline and dopamine were significantly elevated without elevation in serum adrenaline levels. This may be the first report in which radionuclide ventriculography was used to document the time course of normalization in LVEF following removal of a pheochromocytoma.
儿茶酚胺诱导的心肌病与嗜铬细胞瘤相关，是一种已被充分认识但罕见的病症。肥厚型和扩张型变体均有描述。我们报告一例与良性嗜铬细胞瘤相关的扩张型心肌病病例，该病例在肿瘤切除后左心室收缩功能完全恢复正常。血清去甲肾上腺素和多巴胺显著升高，而血清肾上腺素水平未升高。这可能是首例使用放射性核素心室造影记录嗜铬细胞瘤切除后左心室射血分数（LVEF）恢复正常时间进程的报告。
