There are dozens of subtypes of lymphomas. At MR nodules are hypointense or isointense on T1-weighted images T1-WI and hyperintense on T2-WI and demonstrate reduced enhancement after administration of gadolinium Gd compared with normal spleen [ 2 ]. In these forms of lymphoma, such as follicular lymphoma, watchful waiting is uodgkin the initial course of action.

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. In patients with FDG-avid lymphomas, a complete metabolic response after therapy is a good indicator that the patient will remain disease-free in the long term.

HD rarely involves the gastrointestinal GI tract. Isolated peritoneal involvement without accompanying bowel involvement or significant lymphadenopathy with lymphoma is unusual [ 7 ]. Familiarity with the imaging manifestations that are diagnostically specific for lymphoma is important because imaging plays an important role in the noninvasive rettroperitoneal of disease.

Lymphoma may involve the abdominal wall by direct extension from bone or may occur separately in the muscle, subcutaneous fat, retropperitoneal skin from hematogenous spread [ 2 ].

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.

Masses may be sharply circumscribed or may infiltrate into the renal sinus or surrounding tissues [ 1617 ]. The five groups are shown in the table.
