Paula Department of Cardiology of Centro Hospitalar Barreiro-Montijo EPE, Portugal Pericardial cysts (PC) are rare, usually benign, and mostly congenital pericardial anomalies induced by an incomplete coalescence of fetal lacunae during the development of the pericardium. Less frequently, PC are acquired (e.g., postinflammatory, hydatid, neoplastic, traumatic). The presence of a PC poses a diagnostic challenge in distinguishing it from other intracardiac or mediastinal abnormalities. Patients may present with nonspecific chest pain, cough, and dyspnea.
