Neoplastic infiltration of the greater omentum is most commonly caused
by metastatic ovarian, gastric, colonic, or pancreatic carcinoma. Bec
ause the omentum lacks lymphoid elements, lymphomatous infiltration is
uncommon. To date, omental involvement by lymphoma has been reported
exclusively-in patients with non-Hodgkin's lymphomas. In this report,
the computed tomography findings of omental caking caused by Hodgkin's
lymphoma are described. Although rare, both Hodgkin's and non-Hodgkin
's lymphomas should be included in the differential diagnosis of oment
al caking. (C) Elsevier Science Inc., 1996.
