Abstract
The sandwich sign refers to the cross-sectional imaging appearance, most often on CT examination, of mesenteric fat and vessels as the sandwich filling, while the homogeneous soft tissue adenopathy represents sandwich bun. The sandwich sign is due to the presence of large bulky mesenteric adenopathy and is specific to mesenteric lymphomas. Mesenteric lymphomas are unique because they can grow to a large size and can envelop fat, bowel, and vessels without causing clinical symptoms. Most of these mesenteric lymphomas are NHLs. However in patients who have undergone transplantation, PTLD (posttransplant lymphoproliferative disorder), an Epstein–Barr virus-driven B-cell lymphoproliferation in immunosuppressed patients who have undergone transplantation can also create a sandwich sign.
