Primitive Neuroectodermal Tumor of the Heart
The Annals of Thoracic Surgery, 2012We present a case of primitive neuroectodermal tumor of the left atrium with involvement of the coronary sinus. The initial presentation was of cardiac tamponade resulting from the size of the tumor. There was no evidence of tumor elsewhere, and after complete resection and without adjuvant chemotherapy the patient is well at 2-year follow-up.
