Left ventricular aneurysms are outpouchings delineated by a thin myocardial wall, more frequently encountered at the apex of the left ventricle, which is seldom dyskinetic or akinetic. Apart from coronary artery disease, the etiology can be challenging. We report the case of a 30-year-old man with an isolated apical left ventricular aneurysm associated with prominent trabeculations on echocardiography.

左心室室壁瘤是由薄心肌壁界定的膨出，更常发生于左心室心尖部，该处室壁瘤很少出现运动障碍或无运动。除冠状动脉疾病外，病因可能具有挑战性。我们报告了一例 30 岁男性的孤立性左心室心尖部室壁瘤病例，该患者伴有超声心动图上明显的小梁结构。
