Malignant primary cardiac tumour presenting as superior vena cava obstruction syndrome

A 71-year-old male with a malignant primary cardiac lymphoma nearly filling the right atrium presented with symptoms of obstruction of the tricuspid valve and inflow to the right atrium. The tumour was resected as fully as possible; however, a portion of the tumour that had invaded the inferior aspect of the right atrium and the atrioventricular groove could not be excised. Eighteen months after initial presentation, the patient is well and the tumour has not recurred. This is the first case of symptom-free survival of primary cardiac lymphoma for as long as 18 months.
