A Ball in the Heart: An Interesting Discovery in a Very Rare Cardiac Tumor

Abstract

Primary pericardial malignant mesothelioma is an extremely rare tumor even among all mesotheliomas with about 350 cases reported in the literature so far. Typically, it has an insidious presentation, with nonspecific signs and symptoms, and usually results in constrictive pericarditis, cardiac tamponade or congestive heart failure through either a massive effusion or direct tumurous constriction or invasion to the heart. With the exception of several case reports, the outcome is uniformly dismal and patients typically die within six months of diagnosis. We report a 24 year old male with long history of pleuretic chest paint and admissions with a diagnosis of idiopathic pericarditis, eventually presenting with increasing symptoms of heart failure and a large mobile ball like mass in the heart at echocardiographic and computed tomography studies. At operation, an atypical invasive cardiac tumor was discovered. Complete resection of the tumor was impossible and the patient died from progression of the disease 4 months later.
