title: Atypical radiographic features in Pneumocystis carinii pneumonia.
abstract: In a review of clinical, pathologic, and radiographic findings from 30 patients with confirmed pneumocystis pneumonia, the disease presented a typical radiographic picture of acute bilateral perihilar and basilar infiltrate progressing to diffuse alveolar consolidation within 3-5 days and unassociated with adenopathy or pleural changes in 13 patients. However, the incidence of atypical radiographic features was appreciable (17 of the 30 patients showed at least one atypical finding) and, in addition, few radiographic findings completely excluded the diagnosis of pneumocystis infection.
