本文报告一例尸检发现仅侵犯心肌和心包的巨大细胞淋巴瘤。临床症状以心衰开始,继而迅速呈进行性心脏阻滞。其诊断由镓及同位素血池检查而提示,后经心肌活检证实。临床经过突然,未能治疗病人即死亡。本病极为罕见。本例经验提示无创性同位素检查尤其镓和同位素血池检查在非典型心肌病的诊断中有相当价值。Davies 未曾认清本病,Olsen 和Hudson 仅作过概述。昔日报告的少数病例均系死后确诊。本文证实该例确属心脏原发性淋巴瘤,且以心肌梗塞伴有心力衰竭的临床表现起病,使诊断未能明确。之后临床 This article reports a case of autopsy found only infringing the myocardium and pericardial giant cell lymphoma. Clinical symptoms start with heart failure, followed by rapid progressive heart block. The diagnosis of gallium and isotope blood pool check prompted, confirmed by myocardial biopsy. After a sudden clinical failure to treat the patient died. The disease is extremely rare. Our experience suggests that noninvasive isotope examination, especially gallium and isotope blood pool examination, is of considerable value in the diagnosis of atypical cardiomyopathy. Davies did not recognize the disease, Olsen and Hudson only made an overview. A few cases reported in the past were diagnosed after death. This article confirmed that the case is indeed a primary cardiac lymphoma, and myocardial infarction with clinical manifestations of heart failure onset, the diagnosis failed to clear. After the clinical
