Left ventricular (LV) diverticulum represents a rare and frequently asymptomatic congenital anomaly, which is incidentally discovered during routine transthoracic echocardiography. We present a case of a 66-year-old female patient who was admitted to the cardiology department due to incidental finding of a tumor-like mass associated with the posterior mitral leaflet. Preliminary echocardiographic evaluation revealed a solid structure, suspected of mitral annulus calcification or LV malignancy. However, cardiac contrast-enhanced computed tomography confirmed the presence of LV diverticulum, partially filled with calcified thrombus. Conservative management was recommended. This case underscores the importance of multimodality imaging for differentiation of LV tumor-like structures.
左心室憩室是一种罕见且常无症状的先天性异常，常在常规经胸超声心动图检查时偶然发现。我们报告一例66岁女性患者，因偶然发现与二尖瓣后叶相关的肿瘤样肿块而入住心内科。初步超声心动图评估显示为实性结构，怀疑是二尖瓣环钙化或左心室恶性肿瘤。然而，心脏对比增强计算机断层扫描证实存在左心室憩室，部分充满钙化血栓。建议采取保守治疗。该病例强调了多模态成像在鉴别左心室肿瘤样结构中的重要性。
