[Features of tomodensitometry in the development of pleuropulmonary lesions related to Wegener's granulomatosis].
OBJECTIVE
The aim of this study was to determine CT scan value for the follow-up of patients with pleuropulmonary lesions related to Wegener's granulomatosis.


METHODS
Retrospective study of ten patients who were diagnosed with diffuse Wegener's granulomatosis including lung involvement and for whom mean follow-up was 23 months (range 4-61).


RESULTS
During early stages of the disease, the most common finding was the existence of either nodules (90% of the patients) or consolidations (100% of the patients). CT scan controls showed that nodules disappeared within 6 months in 60% of patients and had completely resolved after 12 months. Linear opacities relating to traction developed, replacing subpleural nodules. A pneumothorax occurred in two patients who had excavated subpleural nodules. Consolidations disappeared in 44% of the patients, most frequently within 4 months. When consolidations persisted, they were replaced by alveolar infiltrates accompanied by bronchiolectasies and linear opacities. Regarding either nodules or consolidations, CT features related to relapse were similar to those of initial lesions in 40% of the cases.


CONCLUSIONS
The main features of pleuropulmonary lesions relating to Wegener's granulomatosis were subpleural nodules that either disappeared with, however, subsequent linear opacities sequelae, or were complicated by the occurrence of pneumothorax.
