A case of epicardial cyst.

Epicardial Cyst Originating from Right Ventricle

“…Usually, a pericardial cyst is composed of a single layer of flat or cuboidal mesothelium containing clear, yellowish fluid [5,6]. However, our cyst did not have a mesothelial lining and contained blood-like material.…”

Epicardial Cysts: Report of Two Rare Cases

“…Although many authors have reported several cases of pericardial cysts, the incidence of epicardial cysts originating directly from the epicardium is extremely low. Including the first report of Edwards and Ahmad, only 6 cases in total have been reported to date [Edwards 1972;Komeda 1985;Ozasa 1991;Scrofani 2002;Omeroglu 2004;Buyukates 2008]. We report herein 2 cases of multiloculated epicardial cysts that were successfully excised.…”

“…Epicardial cysts are often diagnosed incidentally, unless they expand and cause compression-related symptoms as in our case. The differential diagnosis includes cystic lesions of the mediastinum such as teratomatous and bronchogenic cysts, lymphangiomas, pericardial fat tissue, lung tumors and lymphomas [Ozasa 1991]. Epicardial cysts are commonly unilocular, but they may become multilocular due to constrictive fibrous bands as in the first case.…”

An Epicardial Mesothelial Cyst Attached to the Ascending Aorta

“…An epicardial mesothelial cyst, which can be defined as a mesothelial cyst attached to the epicardium surrounding the heart and great vessels inside the pericardial sac, is an extremely rare condition [Omeroglu 2004] . To our knowledge, only nine cases with a clear pathological documentation of mesothelial cell origin have been reported to date [Beirne 1954;Debus 2001;Edwards 1972;Hatemi 2012;Komeda 1985;Omeroglu 2004;Ozasa 1991;Scrofani 2002]. Epicardial cysts are histologically identical to pericardial mesothelial cysts, which are much more common.…”

“…We herein report a case of epicardial cyst, which was attached to the ascending aorta. To our knowledge, only nine cases with clear documentation of mesothelial cell origin have been reported to date [Beirne 1954;Debus 2001;Edwards 1972;Hatemi 2012;Komeda 1985;Omeroglu 2004;Ozasa 1991;Scrofani 2002] and the attachment to the ascending aorta has never been reported before.…”
