A 24-year-old man was hospitalized for an investigation of cardiac enl
argement. Serum hyaluronic acid was increased to 238 ng/ml. Echocardio
gram showed pericardial effusion with an area of increased density adj
acent to the anterolateral wail of the left ventricle. A soft-tissue m
ass within the pericardial space was enhanced with gadolinium DTPA on
magnetic resonance imaging. Open biopsy confirmed the presence of a ma
lignant mesothelioma. Magnetic resonance imaging provided useful infor
mation regarding the tumor.
