Epicardial cyst eroding left ventricular wall mimicking as simple
pericardial cyst: a case report
Epicardial cysts are rarer benign tumors than pericardial cysts. 17-
year old boy presented with chest pain and palpitations and was
diagnosed as mediastinal mass (pericardial cyst) on the basis of MRI and
echocardiography. Surgical resection via thoracotomy was planned.
Intraoperatively, the cyst was found to be epicardial in origin with
close proximity to posterior descending artery. Therefore resection was
concluded via midline approach and cardiopulmonary support. Despite
detailed preoperative investigation and assessment, misdiagnosis of
cardiac masses cannot be completely ruled out. Any undesired
intraoperative diagnosis should be carefully dealt and a safer
alternative approach can be considered for a better outcome.
