Discussion
Lymphomatous involvement of the mesentery and retroperitoneum occurs in 4-5% of cases of Hodgkin’s lymphoma and up to 50% of non-Hodgkin’s lymphoma. This is best demonstrated on CT. Involvement ranges from clusters of small nodes to confluent soft tissue masses. The classic CT appearance of mesenteric lymphoma is confluent lobulated soft tissue mass encasing branches of the superior mesenteric artery and vein to create the “sandwich” or “hamburger” sign. There may be concomitant retroperitoneal and inguinal adenopathy, and hepatosplenomegaly. Differential diagnosis of mesenteric adenopathy includes metastatic disease, reactive adenopathy, granulomatous disease, and Whipple’s disease.
