The WHO classification, published in and updated in  is based upon the foundations laid within the “revised European-American lymphoma classification” REAL. Axial contrast-enhanced CT images A, B show bulky heterogeneous masses within the greater omentum asterisks, A, B with no associated ascites or enlarged lymph nodes.

In patients with FDG-avid lymphomas, a complete metabolic response after therapy is a good indicator that the patient will remain disease-free linfoms the long term.
The entities included in the highly aggressive group are Burkitt lymphoma and lymphoblastic lymphoma.

After lymphoma is diagnosed, a variety of tests may be carried out to look for specific features characteristic of different types of lymphoma. The Merck Manual of Geriatrics.

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 ].

Ascites is a frequent finding in carcinomatosis, and may be moderate to large volume. Vascular invasion, pancreatic atrophy retroperitoeal to the tumor, and tumor calcification and necrosis are unusual at initial presentation. Treatment of the nonsymptomatic patient is often avoided. Enlarged LN can be fused together and form a huge mass and can be seen on CT as uniform density lesions with mild homogenous enhancement [ 3 ].
However, secondary liver involvement is fairly common and is usually associated with lymph node disease. Small omental nodules associated with fine infiltration of the omental fat producing a smudged appearance can also be encountered Fig.
