The computed tomographic appearances in chronic berylliosis.

Computed tomography (CT) of the thorax was performed in eight patients with chronic berylliosis. The pulmonary CT features were variable and included pulmonary nodularity, and patterns consistent with upper lobe fibrosis or diffuse interstitial fibrosis. Mediastinal or hilar lymphadenopathy was shown in three cases. CT clearly demonstrates the pattern and distribution of pulmonary and mediastinal involvement in chronic pulmonary berylliosis but the appearances are non-specific.
