Left ventricular (LV) apical thrombus can rarely occur during the early phase of takotsubo cardiomyopathy. We report such a case that was depicted clearly in contrast computed tomography (CT) but not in initial echocardiography. Because LV thrombus may lead to thromboembolic events, we should evaluate all patients with takotsubo cardiomyopathy for the presence of a LV thrombus. LV thrombus is generally recognized with echocardiography in the course of follow-up, but limited depiction of the LV apex with echocardiography can make evaluation of LV thrombus difficult. Contrast CT is useful to detect LV apical thrombus associated with takotsubo cardiomyopathy.
左心室（LV）心尖部血栓在应激性心肌病早期很少发生。我们报告了这样一例病例，其在对比计算机断层扫描（CT）中显示清晰，但在初始超声心动图中未显示。由于左心室血栓可能导致血栓栓塞事件，我们应评估所有应激性心肌病患者是否存在左心室血栓。左心室血栓通常在随访过程中通过超声心动图得以识别，但超声心动图对左心室心尖部的显示受限会使左心室血栓的评估变得困难。对比CT对于检测与应激性心肌病相关的左心室心尖部血栓很有用。
