Multimodalities Imaging in Diagnosis of Pericardial Cyst.

Pericardial cysts, an uncommon benign congenital anomaly belonging to the category of mediastinal masses. Cysts are usually detected incidentally on chest radiography or echocardiography, being most patients asymptomatic. In some cases, however, symptoms and complications occur, like dyspnea, chest pain, or persistent cough. Computed tomography and magnetic resonance imaging are the imaging techniques of choice to diagnose pericardial cysts. The removal of pericardial cysts is restricted to the cases with an uncertain diagnosis or in the presence of symptoms.
