Right atrial hemangioma presenting as pericardial tamponade. A case report

Intracardiac haemangioma is a very rare benign primary cardiac tumour. A 40-year-old patient, with no notable history, presented with chest pain, accentuated by deep inspiration, associated with NYHA stage III dyspnoea. Physical examination revealed signs of right heart failure and electrocardiogram showed low voltage with diffuse repolarization disorders. Chez x-ray showed a cardiothoracic index CTI > 0.70, and enlarged right margins. A large pericardial effusion with a tumour mass filling the right atrial cavity was discovered on transthoracic echocardiography. Chest computed tomography demonstrated the tissue origin of the tumour and suggested extension to the inferior vena cava and hepatic veins. The patient was referred to a surgeon for tumour resection. Histological examination revealed intracardiac capillary haemangioma. Five month postoperative follow-up did not reveal any abnormalities.
