Diffuse lymphomatous infiltration of the mesentery produces a stellate appearance of the mesentery and causes fixation of the small bowel loops [ 2 ]. Lymphoma involving both kidneys.

The radiographic, CT, and barium examination features of intrinsic bowel involvement are similar in patients with AIDS and immunocompetent patients, and no gross morphologic differences among the different histologic types are found [ 1718 ]. Some authors believe this is actually the only existing form of renal lymphoma. The ureter is often affected by involved retroperitoneal nodes, but primary involvement of the ureter by lymphoma is rare. Advanced Hodgkin disease requires systemic chemotherapy, sometimes combined with radiotherapy.
