[CT findings of pulmonary sarcoidosis]

A retrospective review was performed on CT findings in 46 patients of pulmonary sarcoidosis proven by histology. Pulmonary lesions were detected in 26 patients (56.5%). Frequent CT findings were peribronchial markings (69.2%), diffuse small nodules (65.4%), pleural lesions (38.5%), lymphangitis carcinomatosa like changes (30.8%), and large irregular nodules (30.8%). Follow up CTs were obtained in 18 patients. Peribronchial markings and diffuse small nodules had tendency to improve, although atelectasis, pleural thickening, and bullae were irreversible and progressive. CT plays an important role in the diagnosis and have a prognostic value in pulmonary sarcoidosis.
