Primary cardiac epithelioid angiosarcoma with frond-like features: a rare and ominous radiological mimicker of benign cardiac tumors

Most primary cardiac tumors are benign neoplasms, which generally can be differentiated from malignant neoplasms via certain radiological features. We present briefly a case of a 26-year-old man undergoing resection of a right atrial mass that based on preceding radiologic findings represent a myxoma. After pathologic examination, the lesion was determined to be an epithelioid angiosarcoma with unique frond-like architecture and multiple pedicular attachments to the atrial wall.
