Pericardial mesothelial inclusion cyst leading to right heart failure

Abstract

Pericardial mesothelial inclusion cysts are usually benign intrathorasic lesions, which locate aberantly and originate from coelomic space. Despite asymptomatic nature, they may infect or compress to the adjacent structures in larger sizes. The diagnosis is usually made coincidentally by chest X-ray. In this article, we present a 57-year-old female case who was admitted with the complaints of dyspnea and swollen legs and in whom a paracardiac mass was detected by chest X-ray radiography in the light of literature data.
