Lymphatic changes in retroperitoneal lipomatosis.
Retroperitoneal lipomatosis is a condition in which excessive fat deposits in the retroperitoneum can exert a mass effect, with displacement of normal structures. In the case presented, it displaced lymph nodes and simulated adenopathy in nonopacified nodes. The specific diagnosis of retroperitoneal lipomatosis as the cause of the mass effect can be made by computerized tomography.
