Abstract
- 8 patients with pathologically proven pleural mesothelioma(5 localized type, 3 diffuse type), and 1 patientswith malignant pericardial mesothelioma, were examined by computed tomography(CT), and obatined sime results asfollows; 1. Pleural Mesonthelima a. Localized pleural mesothelioma 4 cases were benign and 1 case was 1 case wasmalignant in microscopic examination. CT showed invariably sharply marginated pleura-based soft tissue mass andthe density of the mass was variable, homogenous in small tumor but inhomogenous with low density area in largerone, and even calcification was seen in one of them. The angle of pleura-mass interface was obtuse in only onesmall tumor and acute with smooth tapering end in four larger tumor. b. Diffuse pleural mesothelima (DPM) Multiplenodular pleural masses encompassing nearly entire lung were seen with associated multiple subplerual parenchymal nodule & localized axial interstitial thickening in two case. Protruding chest wall mass with destruction of ribwas seen in previous pneumonectomized thorax. Minimal pleural effusion/thickening was also seen in all. 2. Pericardial mesothelioma Pericardial fluid and multiple nodular masses, which occupied pericardial sac up tosuperior sinus were well delineated on CT. It had been misinterpreted as pericardial effusion for years on echocardiogram.
