Computed tomography in the diagnosis of renal carcinoma complicating Hippel-Lindau syndrome

Abstract

Four patients on long-term follow-up for Hippel-Lindau syndrome (HLS) are presented. All had undergone nephrectomy for renal carcinoma; in 2, carcinoma subsequently developed in the remaining kidney. Because of the tendency of these tumors to develop bilaterally, wide local resection is preferable to radical nephrectomy if the tumors can be diagnosed when small and noninvasive. CT is currently the most accurate method of regularly screening patients with HLS for asymptomatic renal carcinoma.
