An undifferentiated, pleomorphic cardiac sarcoma masquerading as myxoma

Cardiac sarcoma is a very rare cause of primary cardiac tumor. We present a case of an undifferentiated, pleomorphic cardiac sarcoma, masquerading as a cardiac myxoma on multimodal imaging evaluation, which was definitively diagnosed on intra-operative histopathologic examination followed by surgical resection. Learning objective: Evaluate and diagnose a rare primary cardiac tumor via multimodal imaging and a multidisciplinary approach.
