title: MRI appearance of pulmonary Wegener's granulomatosis with concomitant splenic infarction.
abstract: The MRI appearance of pulmonary lesions in a patient with Wegener's granulomatosis is presented. Pulmonary involvement was characterized by multiple solid and cavitated nodules connected to vessels. Transbronchial biopsy demonstrated typical findings of granuloma. The spleen presented diffuse low signal intensity and an enhancing capsule on T1-weighted images, and inhomogeneously high signal intensity on T2-weighted images. This appearance of diffuse infarction could result from the vasculitis caused by Wegener's disease.
