Abstract
PURPOSE OF REVIEW
This is an in-depth review on the etiology, clinical manifestation, differential diagnosis, diagnostic modalities, complications, and management of pericardial cysts (PCs).
RECENT FINDINGS
PCs are the third most common type of mediastinal masses and are usually identified incidentally by chest x-ray (CXR) or transthoracic echocardiography (TTE). Although most PCs are asymptomatic, they might lead to serious complications such as cardiac tamponade. Diagnosis is confirmed by cardiac computed tomography or cardiac magnetic resonance. Cysts need to be followed by imaging every 1 to 2 years; however, a recent report suggested less frequent follow-up. Most cases resolve spontaneously, but if needed, aspiration or surgical resection can be done. PCs are rare entities and are usually detected incidentally after CXR or TTE. Providers should be aware of this condition since it could potentially lead to serious complications.
