- Abstract
- We report the case of a 53-year-old male patient who presented to the cardiology department with presyncope and atypical chest pain. The transthoracic echocardiography revealed a homogeneous hypoechoic mass measuring 2.5 × 5.7 cm at the level of the anterolateral wall of the right ventricle. In order to further characterize the identified right-ventricle-adjacent mass, we performed a cardiac computed tomography, which confirmed the presence of a homogeneous hypodense mass with a single wall, without septation. Cardiac magnetic resonance imaging demonstrated a serous fluid mass capping the right atrium, right atrial appendage, and coronary sinus, without evidence of myocardial invasion. The multimodality imaging performed clarified the diagnosis of an uncomplicated pericardial cyst. The patient was managed conservatively with every 6 months echocardiographic evaluation. At a 2-year follow-up, he presented no recurrent symptoms, and the pericardial cyst maintained the same characteristics. The cornerstone of this case report was relying on multimodality imaging in order to characterize the adjacent cardiac mass and to arrive at the diagnosis of an uncomplicated pericardial cyst, which established the prognosis and management of the patient.
