title: Excessive accumulation of normal retroperitoneal fat mimicking a neoplasm: urographic/CT correlations.
abstract: Computed tomography (CT) was performed on four patients in whom excretory urograms revealed marked displacement of the kidneys and/or ureters. CT in each case was remarkable for the presence of excessive accumulation of normal retroperitoneal fat and failed to document the existence of a retroperitoneal neoplasm, lymphadenopathy, or other pathological mass.
