title: Computed tomography in pulmonary pseudotumors and their relation to asbestos exposure.
abstract: Twelve patients, nine of whom had histories of exposure to asbestos, were evaluated by chest roentgenography and computed tomography because of a pulmonary mass lesion. The lesion consisted of condensed atelectatic lung parenchyma surrounded by marked thickening of the pleura--a pulmonary pseudotumor. In most patients, the mass lesion was only part of a more extensive disease process with pleural plaques and parenchymal fibrosis. Computed tomography demonstrated the full extent of disease better than chest roentgenograms. Asbestos is stressed as a possible causative factor of these mass lesions.
