Title: CT diagnosis and differential diagnosis of pulmonary Wegener's granulomatosis
Abstract: Objective To characterize CT features of pulmonary Wegener's granulomatosis so as to improve the diagnostic accuracy.Methods Seventeen patients,10 males and 7 females,aged 11-72(mean 37.5)with histopathologically and clinically proved Wegener's granulomatosis were included.All the patients underwent CT plain scan and enhanced scan.Results CT manifestation of pul-monary Wegener's granulomatosis included massive infiltration with blurred margins(n=4),small patchy infiltration(n=5),multiple nodules(less than 3cm in diameter)(n=9),mass(more than 3cm in diameter)(n=2),cavitation(n=11),strip shadow(n=4),ground-glass like shadow(n=3),pulmonary atelectasis(n=2),bronchus narrowing or obstruction(n=2).Some patients presented with varied kinds of lesions,which could transform each other and become more or less.Conclusions Imaging manifestation pulmonary Wegener's granulomatosis is varied.The main manifestation is patchy infilitration,nodules and cavitation.Thin walled cavity and ring-shade cavity are diagnostic.This disease should be differentiated to pulmonary carcinoma,tuberculosis,pneumonia and abscess.
