Pericardial Malignant Mesothelioma

**Semantic type:** Neoplastic Process

**Definition:** A rare malignant mesothelioma that arises from the pericardium. Clinical presentation includes pericardial effusion, congestive heart failure, a mass or cardiac tamponade. Surgical resection is the treatment of choice. Adjunct treatments of chemotherapy or radiation have not improved outcomes. The prognosis is extremely poor due to its late presentation and difficulty obtaining complete surgical excision. In most cases the diagnosis is made at autopsy or postoperatively.
