– The radiographic features of pulmonary sarcoidosis are classified into four stages. In a minority of cases unusual manifestations can be identified in chestradiographs.
In a retrospective study over the years 1975-1985 there were 16 (10) out of 168 patients with pulmonary sarcoidosis, who had one or more of the unusual radiographic manifestations: partial pulmonary atelectasis with consolidation in 6 patients, solitary or multiple large pulmonary nodules in 5, pleural effusion in 3, apparent alveolar infiltrate in 2 and elevation of a hemidiaphragm in 3 patients. We describe the findings in 4 patients in some detail.
The results of the study emphasize that pulmonary sarcoidosis may present with different radiographic images. It is important to bear in mind that the uncharacteristic, radiographic appearances described may be due to sarcoidosis.
