title: Mass lesions of the retroperitoneum (excluding specific organs).
abstract: The value of computed tomography (CT) in the diagnosis and management of retroperitoneal masses is discussed. Neoplastic, inflammatory, and hemorrhagic conditions are shown. In addition to facilitating the detection of these mass lesions, CT is especially valuable in allowing accurate biopsies and aspiration to be performed and in the follow-up of the patient.
