title: Gray scale ultrasound in identification of lymphoma complicating lymphomatoid granulomatosis.
abstract: Lymphomatoid granulomatosis is a necrotizing vasculitis involving multiple organs which may be associated with lymphomatous transformation. A case of lymphomatoid granulomatosis is presented in which gray scale ultrasound identified lymphomatous transformation involving the right kidney and retroperitoneum, thus preventing unnecessary surgery. Ultrasound is a valuable modality for identifying and characterizing abdominal masses in patients at risk for neoplastic disease.
