Pleural mesothelioma is a frequent enough tumor to be considered in the differential diagnosis of chest tumors. The most characteristic symptoms are pain and dyspnea. A history of asbestos exposure or pulmonary asbestosis should alert the radiologist to the possibility of an existing or developing pleural mesothelioma.
The important radiologic manifestations are: (1) pleural effusion, often recurrent; (2) irregular, nodular pleural thickening, with or without bone destruction; and (3) a nodular density, frequently in the peripheral portion of the lung.
The prognosis is poor. Of the 10 patients studied, 7 died; 2 are alive but have persistent disease; and 1 patient, with a small nodular lesion, is cured 44 months following surgery.
