CT of the abdomen demonstrates lymph nodes involving mesenteric vessels sandwich sign anterior to aorta and inferior to vena cava in a patient with retroperktoneal arrows. Patients with these types of lymphoma can live near-normal lifespans, but the disease is incurable. After a diagnosis and before treatment, a cancer is staged. World Health Organization classification of tumours. Archived copy as title link CS1 maint: Peritoneal lymphomatosis is a rare clinical presentation that is often associated with high-grade primary gastrointestinal NHL and is radiologically indistinguishable from peritoneal carcinomatosis [ 215 ].

There is no retroperitoneal lymphadenopathy. Archived copy as title CS1 maint: The WHO classification, published in and updated in[29] [30] is based upon the foundations laid within the “revised European-American lymphoma classification” REAL.

International Journal of Advanced Research. Kidney; Lymphoma; Computed tomography. This purely histological classification included no information about cell surface markersor genetics, retroperitoneap it made no distinction between T-cell lymphomas and B-cell lymphomas.

Lymphomas are broadly subdivided into Hodgkin lymphoma and NHL, based on distinct clinical and histologic features. Young man with NHL. CT findings of lymphoma with peritoneal, omental and mesenteric involvement: A year-old man with Burkitt lymphoma and complete response to treatment after 6 cycles of chemotherapy.

The appearance may vary from one or a few large low-attenuation masses to multiple small nodules. The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques.

The International Prognostic Index used for NHL is based on both imaging and clinical findings, and the stage and the number of extranodal sites of disease are included. Lymphoma is the most common malignancy of the small bowel, and in recent years its incidence related to B-cell hyperactivation in HIV-positive patients has increased.

Diffuse infiltration may be present in spleens of normal size. Focal hepatic lymphoma appears as circumscribed nodules that are hypoechoic and show no posterior acoustic enhancement on US.

Increase in heterogeneous or rim enhancement of LN due to intranodular necrosis after treatment and calcifications of lesions may occur Figure 7 [ 3 ]. The CT manifestations of nodal disease before and after radiochemotherapy are different, including changes in internal nodal characteristics.

Axial CT shows masses involving small bowel loops and ascending colon arrows. Notice the nodular architecture and the areas of “mottling”. The patterns of involvement include a rounded circumscribed homogeneous mass and an enlarged adrenal gland that maintains its normal shape [ 2 ].

The appearance of peritoneal lymphomatosis may overlap with carcinomatosis and sarcomatosis, however bulky homogeneous masses or smooth peritoneal soft tissue thickening, diffuse lymphadenopathy, in addition to imaging features of variable extranodal lymphomatous involvement are contributory findings supporting the lymphoma diagnosis.
