A previously well 45-year-old male presented with 20 days of being generally unwell with a fever and dyspnoea on exertion. Transthoracic echocardiography was done and revealed a round cystic structure (3 x 3 cm) attached to the tricuspid valve. Multiple small calcified particles (daughter cysts) were also seen in the cyst which was most consistent with the diagnosis of Hydatid cyst. The serology for Echinococcus granulosus antibody was positive and confirmed the diagnosis. The patient was sent for cardiac surgery and hydatid cyst which was endocardial in location, and adherent to the tricuspid valve leaflets was the intraoperative finding. The patient improved and was discharged on long-term chemotherapy. The most common cite of cardiac involvement is the myocardium followed by the pericardium, whereas endocardial involvement is extremely rare. In the present study, we demonstrated a very rare case of endocardial hydatid cyst with attachment to the tricuspid valve.
一名既往健康的45岁男性，出现全身不适20天，伴有发热和劳力性呼吸困难。进行了经胸超声心动图检查，发现一个附着于三尖瓣的圆形囊性结构（3×3厘米）。囊肿内还可见多个小钙化颗粒（子囊），这与包虫囊肿的诊断最为相符。细粒棘球绦虫抗体血清学检查呈阳性，确诊了该诊断。患者被送去进行心脏手术，术中发现包虫囊肿位于心内膜，附着于三尖瓣小叶。患者病情好转，出院后接受长期化疗。心脏受累最常见的部位是心肌，其次是心包，而心内膜受累极为罕见。在本研究中，我们展示了一例非常罕见的心内膜包虫囊肿附着于三尖瓣的病例。
