Abstract

Objective: To evaluate CT manifestations and the value of diagnosis of Wegener granulomatosis of lung. Methods: All the CT findings of the 10 cases with Wegener granulomatosis in lung confirmed clinically or by operation were analyzed retrospectively. Results: Nodules and cavitations were seen in 6 patients. Masses with cavitations were seen in 2 patients. Wedge-shaped areas of peripheral consolidation without uniform density abutting the pleura were seen in 2 patients. A feeding vessel sign to a nodule or mass were seen in 5 patients. Ground-glass attenuation and consolidation were seen in 4 patients. Bronchial wall thickening was discovered in 4 patients, tracheostenosis was seen in 1 patient, bronchiectases were found in 3 patients. Pleural irregularities were seen in 1 patient and pleural effusion was seen in 1 patient. Conclusion: Nodules and cavitations, wedge-shaped areas of peripheral consolidation, ground-glass attenuation and consolidation in lung are specific signs in diagnosing Wegener granulomatosis in lung. A feeding vessel sign to a nodule or mass is also one of its important characteristics, and all these special developments are more important for us to diagnose Wegener granulomatosis in lung.
