The authors report the case of a 36-year-old male who, following investigations for dyspnea, othopnea and peripheral cyanosis, was found to have metastatic intracardiac plasmacytoma. Diagnosis was made initially with transesophageal echocardiography and emergent cardiac surgery was performed. Postoperative transthoracic and transesophageal echocardiograms revealed residual masses in the right and left atrium. The patient was subsequently treated with systemic chemotherapy and was symptom-free within three months of treatment, with rapid decline of paraproteins in the serum and urine. This case of intracardiac metastatic plasmacytoma is deemed unique because cardiac involvement with multiple myeloma has not been studied in detail, largely due to the rarity of such a presentation.
作者报告了一例36岁男性病例，该患者在因呼吸困难、端坐呼吸和外周发绀接受检查后，被发现患有转移性心内浆细胞瘤。最初通过经食管超声心动图做出诊断，并进行了急诊心脏手术。术后经胸和经食管超声心动图显示右心房和左心房有残留肿块。该患者随后接受了全身化疗，治疗后三个月内症状消失，血清和尿液中的副蛋白迅速下降。这例心内转移性浆细胞瘤病例被认为是独特的，因为多发性骨髓瘤累及心脏尚未得到详细研究，主要是由于这种表现非常罕见。
