They are usually asymptomatic and diagnosed incidentally on echocardiography or chest X-ray. In this report, we present an extremely rare case of a symptomatic giant pericardial cyst (11.6 cm × 10.6 cm × 8 cm) of a 55-year-old male patient who was admitted to our cardiology clinic. A thoracic computed tomography (CT) in 2013 revealed a giant pericardial cyst. However, at that time, the patient was asymptomatic and follow-up was recommended. Recent thoracic CT and magnetic resonance imaging demonstrated a significantly growing feature of this cyst with impending possible complications. © 2018 Nigerian Journal of Clinical Practice | Published by Wolters Kluwer - Medknow.eninfo:eu-repo/semantics/closedAccessComputed tomographyGiant pericardial cystMediastinal cystArticleQ4Q2211111113PubMed:294117340
