Case Discussion

This 75 year-old female with known chronic lymphocytic leukaemia presented in extremis with abdominal pain, abdominal distention, acidosis and elevated lactate. A CT was performed for possible ischaemic colitis.

There is caecal pneumatosis and dilatation consistent with ischaemia. There is also a mesenteric and para-aortic nodal mass with the hamburger sign suggesting lymphoma.

Americans may try to tell you this is the sandwich sign. The sign is specific for mesenteric lymphoma (typically non-Hodgkin) unless the patient has had a transplant. If so, posttransplant lymphoproliferative disorder should be considered.
