    Journal: Nihon Kokyuki Gakkai Zasshi; 2002 Feb; 40(2):171-6. PubMed ID: 11974875.
    Abstract:
    We reviewed the chest radiographs and serial CT scans of two patients with pathologically confirmed Wegener's granulomatosis. The radiographs revealed multiple nodules or masses with and without cavitation, as well as consolidations. Lung lesions on CT included multiple pulmonary nodules and masses of varying size, cavities, consolidations with air bronchogram. Bronchovascular bundle thickening and lymph node swelling were also seen on CT. Some lung nodules or masses demonstrated feeding vessels or wedge-shaped lesions, or both, abutting the pleura. Follow-up CT before treatment showed that the multiple nodules had increased in size, resulting in masses and consolidations with air bronchogram. After treatment, almost all nodules disappeared without scarring, while the masses and consolidation resolved with residual scarring, and the cavity was transformed to a cystic lesion by follow-up CT. The bronchovascular bundle thickening and lymph node swelling showed improvement.
