Left ventricular thrombus mimicking primary cardiac tumor in a patient with primary antiphospholipid syndrome and recurrent systemic embolism
open access
Abstract
In this report we describe a 39 year-old man admitted to hospital presenting with left hemiparesis and a peripheral embolism. He had no history of thrombotic events. Transthoracic echocardiography showed a large, polypoid and mobile mass (4.0 × 1.2 cm) attached to the apex of the left ventricle, highly suggestive of primary cardiac tumor. The patient subsequently underwent open heart surgery. The histological examination showed an older thrombus and a fresh thrombus. Post-operative laboratory tests showed lupus anticoagulant activity, confirming the primary APS diagnosis. The patient initiated treatment with oral anticoagulation (INR levels between 2 and 3) and was discharged 29 days after surgery. At ten month follow-up, he was symptom-free with long-term anticoagulation therapy. No evidence of intracardiac mass recurrence on two-dimensional echocardiography was seen.
Intracardiac thrombus has been rarely reported as a complication of primary APS. Left ventricular mass mimicking primary cardiac tumor with recurrent systemic embolism has not been previously reported. Pre-operative investigations could not distinguish such a thrombus from a cardiac tumor and the diagnosis was made post-operatively.
