Incidental cardiac lymphangioma misdiagnosed as atrial thrombus: A case report

Cardiac lymphangioma is a characteristically benign primary neoplasm of the heart, previously reported only in a handful of cases. A right atrial lesion was found of a 56-years old healthy male patient. The lesion was surgically excised and identified as cardiac lymphangioma in postoperative pathological analysis. While open surgical tumor resection is preferred in patients with cardiac lymphangioma, preoperative characterization of suspected lesions may warrant conservative management in selected cases.
