Huge Pericardial Cyst with Compressing Effects on the Right-Heart Chambers

Abstract

Introduction: Pericardial cysts are rare abnormalities of the mediastinum and generally have a benign course. Patients are mostly asymptomatic, and diagnosis is established incidentally in a majority of cases. The management of this asymptomatic population is also controversial. Case Report: We report a huge pericardial cyst, located at the right cardiophrenic angle impairing ventricular filling properties without causing evident symptoms. The cyst was almost 13 cm in the largest diameter. Echocardiography and computed tomography scan were utilized not only to confirm the diagnosis, but also to determine the treatment strategy. Conclusions: Surgical or percutaneous interventional treatment for pericardial cysts might be occasionally necessary, depending on the location of the cyst and its relationship with the adjacent structures. Unfortunately, our patient refused any kind of treatment option. Based on this report, the course of the disease, diagnostic modalities, and treatment strategies in general manner were additionally discussed.
