Pulmonary cryptococcosis is caused by Cryptococcus neoformans, a world-wide distribution unimorphic fungus that exhibits the same form in its natural habitat, animals and humans. The disease presents variable clinical and pathologic features and occurs in immunocompetent and immunocompromised patients. We reviewed the computed tomography findings of 14 patients with confirmed pulmonary cryptococcosis. The most frequent computed tomography findings were masses and pulmonary nodules. Other abnormalities included cavities, areas of consolidation, peribronchovascular interstitial thickening and diffuse linear opacities. Pulmonary masses were the most frequent findings (64.2%), followed by nodules (35.7%) whereas diffuse pulmonary disease accounted for 14.2% of the cases. The most affected areas were the upper lobes and the anterior regions. Computed tomography scan of the chest allows a precise assessment of pulmonary parenchymal involvement in patients with pulmonary cryptococcosis.
