Case Discussion
A sandwich sign, sometimes known as a hamburger sign, refers to a mesenteric nodal mass, either para-aortic or not, giving an appearance of a hamburger.
The sign is specific for mesenteric lymphoma (typically non-Hodgkin), unless the patient has had a transplant. If so, post-transplant lymphoproliferative disorder should be considered.
