A Large Pericardial Cyst in a Twelve-Year-Old Boy: A Case Report

Introduction: Pericardial cyst (PC) is a rare disease in pediatrics. The most common cause of PC is congenital abnormalities. Case Presentation: A 12-year-old boy presented with a history of chronic cough and syncope episodes. Due to cardiac symptoms, an initial ECG and transthoracic echocardiography (TTE) were performed. A large extra-cardiac cyst measuring 85 × 70 mm on the roof of the left atrium was reported. Cardiac computed tomography angiography (CTA) confirmed this finding. Due to the patient’s symptoms, excision of the PC was recommended and successfully performed. Conclusions: Pericardial cyst is a rare disease in pediatrics. In symptomatic cases and large pericardial cysts (PCs), similar to our case, surgical management can be a safe and effective treatment.
