A rare case of a cardiac calcified thrombus originating from right atrium and inferior vena cava.

Cardiac calcified thrombus is a rare non-neoplastic cardiac mass that can present like an intra-cardiac tumor. The finding of a calcified thrombus in the inferior vena cava is described in patients with permanent central venous line or in presence of recurrent pulmonary embolism. The aim of the study is to describe a rare case of cardiac calcified thrombus in patient without comorbidities. We report an extremely unusual case of a 73 year-old woman with a calcified thrombus between the inferior cava and the atrium who was admitted to hospital for an incidental evidence of a heart neoformation mimicking a myxoma at an echocardiogram exam, totally asymptomatic performed as a screening test after thyroidectomy. Surgical removal of cardiac mass is fundamental both to achieve the correct diagnosis and to avoid thromboembolic risks or inferior vena cava occlusion. In a patient without serious comorbidities, surgical excision can be performed without major risks.
