Cardiac metastasis from small cell lung cancer (SCLC) origin is rare, whereas the incidence is anticipated to increase with the extended survival rates.
We here describe a case report of a 48-year-old male patient diagnosis with SCLC in 2020. In June 2021, he resorted to hospital due to shortness of breath, no obvious changes were found in repeated echocardiography, electrocardiogram and chest computer tomography from June 2021 to September 2021. Due to the persistence of the complaints, cardiac magnetic resonance (CMR) imaging was performed in September 30th, 2021, which showed a mass in the right atrioventricular groove. The patient underwent pericardiocentesis and small cell carcinoma cells were found in the pericardial effusion, confirming the diagnosis of cardiac metastasis.
Patients with a history of SCLC who develop new cardiac symptoms of unknown etiology should undergo imaging studies such as CMR. The importance of CMR for patients with SCLC is highlighted. The literature regarding metastatic cardiac tumors is reviewed.
小细胞肺癌（SCLC）起源的心脏转移较为罕见，但随着生存率的延长，预计其发病率将会增加。
我们在此描述了一例 48 岁男性患者，该患者于 2020 年诊断为 SCLC。2021 年 6 月，他因呼吸困难就诊，2021 年 6 月至 2021 年 9 月期间，重复进行超声心动图、心电图和胸部计算机断层扫描，均未见明显变化。由于症状持续存在，于 2021 年 9 月 30 日行心脏磁共振（CMR）成像，显示右房室沟有一肿块。患者行心包穿刺术，在心包积液中发现小细胞癌细胞，确诊为心脏转移。
对于出现新的不明原因的心脏症状的 SCLC 病史患者，应进行 CMR 等影像学检查。强调了 CMR 对 SCLC 患者的重要性。复习了转移性心脏肿瘤的文献。
