Metastasis of non-small cell lung carcinoma (NSCLC) is a rare cause of cardiac metastatic tumors (CMT). We present a case of NSCLC infiltrating the apical left ventricle mimicking cardiac aneurysm and tamponade. The patient, who had a history of NSCLC, presented with acute shortness of breath and an echocardiogram concerning for ruptured left ventricular aneurysm. A neoplastic mass found at the cardiac apex suggested CMT leading to ventricular wall rupture and cardiac tamponade. Transthoracic echocardiography is the most ubiquitous imaging modality for CMT diagnosis, with cardiac magnetic resonance imaging offering a more detailed assessment. CMT from NSCLC can cause dangerous cardiac tamponade, warranting consideration in patients with suspected metastases.
非小细胞肺癌（NSCLC）转移是心脏转移性肿瘤（CMT）的罕见原因。我们报告一例NSCLC浸润左心室心尖部，酷似心脏动脉瘤并导致心脏压塞的病例。该患者有NSCLC病史，因急性呼吸急促就诊，超声心动图提示左心室动脉瘤破裂。在心尖部发现的肿瘤性肿块提示CMT导致心室壁破裂和心脏压塞。经胸超声心动图是CMT诊断中最常用的成像方式，心脏磁共振成像可提供更详细的评估。NSCLC引起的CMT可导致危险的心脏压塞，疑似转移的患者需考虑这一情况。
