Case of tumor neovascularization demonstrated by cardiac catheterization

A 46-year-old man presented to his physician with nonspecific abdominal complaints. CT of the abdomen was obtained to investigate his symptoms, which showed significant pericardial effusion. One week after drainage of the pericardial fluid, his symptoms recurred and a transesophageal echo showed a right atrial tumor. Cardiac catheterization demonstrated right coronary artery neovascularization. A nonresectable primary angiosarcoma was found following median sternotomy and biopsy.
