Pericardial mesothelioma cyst occurs rarely, and is often found incidentally. The coexistence between large pericardial mesothelial cyst and hypertrophic obstructive cardiomyopathy (HOCM) can make difficulties in medical management.
Our case was a 33-year-old man presented with dizziness and pallor while standing since four years before, and recent syncope. On admission, transthoracic echocardiography reveled presence of hypertrophic cardiomyopathy in association with relatively small right ventricular and atrium due to compression effect by a large echo-free space at the right side of heart suggestive of pericardial cyst. Cardiac computed tomography confirmed presence of HOCM and large pericardial cyst. Patient underwent surgical septal myectomy and large mesothelial pericardial cyst excision because of persistent symptoms and compression effect of cyst on the right chambers despite beta-blocker therapy.
To best of our knowledge, the coexistence of the large pericardial mesothelial cyst and HOCM has not been reported before.
心包间皮瘤囊肿很少见，常为偶然发现。巨大心包间皮囊肿与肥厚性梗阻性心肌病（HOCM）并存会给医疗管理带来困难。
我们的病例是一名33岁男性，自四年前起站立时出现头晕和面色苍白，近期发生晕厥。入院时，经胸超声心动图显示存在肥厚性心肌病，由于心脏右侧一个提示心包囊肿的大无回声区的压迫作用，右心室和右心房相对较小。心脏计算机断层扫描证实存在HOCM和巨大心包囊肿。尽管使用了β受体阻滞剂治疗，但由于症状持续且囊肿对右心腔有压迫作用，患者接受了外科室间隔心肌切除术和巨大间皮心包囊肿切除术。
据我们所知，此前尚未报道过巨大心包间皮囊肿与HOCM并存的情况。
