Clinical Information

  • This is a rare tumor. Approximately 100 to 150 cases have been reported in the literature. In most cases the diagnosis is made at autopsy or postoperatively. Clinical signs and symptoms include: pericardial effusion, congestive heart failure, a mass or tamponade. The prognosis for pericardial mesothelioma is extremely poor due to its late presentation and difficulty in completely removing it surgically. Surgical resection remains the treatment of choice. Addition of chemotherapy or radiation have been disappointing.
