Pericardial Celomic Cysts

Pericardial celomic cysts are uncommon in occurrence. No unanimity of opinion exists regarding their cause, although the theory that they result secondary to a developmental irregularity of the primitive lacunae, appears to be most feasible. When symptoms are present they are usually the result of mediastinal compression. Differential diagnosis should include elimination of such tumors as teratomas, dermoid cysts, lipomas and chondromas. The treatment of choice is surgical excision. Six case reports of pericardial celomic cysts are presented.
