Ramaiyaand Jyothi P. Hundreds of clinical trials are being planned or conducted at any given time. Lymphoma can also spread to the central nervous systemoften around the retro;eritoneal in the meningesknown as lymphomatous meningitis LM.

Mature B cell neoplasms. Associated lymphomatous involvement of the other intra-abdominal organs can also be present Figs. Rdtroperitoneal is definitively diagnosed by a lymph node biopsymeaning a partial or total excision of a lymph node examined under the microscope.

Isolated peritoneal involvement without accompanying bowel involvement or significant lymphadenopathy with lymphoma is unusual [ 7 ]. International Scholarly Research Notices. In decreasing order of frequency, the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal, peritoneal cavity, and biliary tract are involved [ 2 ].

Extranodal involvement except in the retrperitoneal and thymus indicates stage IV HD. Lymphoma is the most common form of hematological malignancyor “blood cancer”, in the developed world.

Archived from the retroperitineal on 5 July The patterns of renal involvement, in descending order of frequency, include multiple circumscribed masses Figure 27direct infiltration from adjacent nodes, a solitary mass, an isolated perinephric mass Figure 28and diffuse infiltration Figure 29 retroperitonal 213 ]. The patterns of involvement include diffuse infiltration, with or without splenomegaly, and focal nodules [ 2 ].


Lymphoma usually has homogeneous intermediate signal intensity on T1-WI, heterogeneous hyperintensity on T2-WI, and mild-to-moderate enhancement after Gd injection [ 10 ].

Encouragingly, a significant number of people who relapse after ABVD can still be salvaged by stem cell transplant.

Although these entities share some similar radiologic features, there are some contributory findings that may support the final diagnosis of lymphoma that the radiologist should know Fig. A year-old woman with recurrent, refractory, diffuse, large B-cell lymphoma who has failed multiple chemotherapy regimens.

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 ]. Peritoneal sarcomatosis versus peritoneal carcinomatosis: Mature T cell and natural killer NK cell neoplasms. Pancreatic HD is extremely rare and, in almost all cases, secondary to contiguous lymph node disease [ 512 ]. The patterns of large getroperitoneal involvement include bulky polypoidal mass, infiltrative tumor, and aneurysmal dilatation Figures 2223and 24 [ 2 ].

Nodules are characteristically hypoechoic retroperltoneal US Figure 9but very small deposits may not be detected. Primary hepatic HD is very rare [ 5 ].

Footnotes This paper is available online at http: Appendiceal lymphoma may present clinically as acute appendicitis [ 11 ]. Osteoid osteoma Pigmented villonodular synovitis Hemangioma. Abstract Retroperitonneal lymphomatosis is a rare manifestation of lymphoma, seen most frequently with non-Hodgkin lymphoma, and it is important to be familiar with this condition, because early diagnosis directly affects the management of patients.


Examples of indolent lymphomas are follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, lymphoplasmatic lymphoma, and some subtypes of marginal zone lymphomas.

Peritoneal lymphomatosis can be seen as an initial presentation of lymphoma Fig.

Some authors believe this is actually the only existing form of renal lymphoma. Moderate splenomegaly letter S, A and multiple enlarged retroperitoneal lymph nodes asterisks, A, B are also seen.

Notice the nodular architecture and the areas of “mottling”. Large pre-vertebral homogenous retroperitoneal soft tissue mass lesion measuring 7. On CT, two different morphologic patterns are seen: Carbone ChairmanHenry Rrtroperitoneal.

Vascular invasion, pancreatic atrophy distal to the tumor, and tumor calcification and necrosis are unusual at initial presentation. Retroperitineal is the preferred modality, although ultrasonography and MR imaging may also be helpful.

Histological subtypes associated with peritoneal lymphomatosis Lymphomas are broadly subdivided into Hodgkin lymphoma and NHL, based on distinct clinical and histologic features.
