Case of the Week: Colonic Lymphoma (CT & PET)

3 minutes

In this radiology lecture, we discuss the imaging appearance of large bowel lymphoma.

Key points include:

Often isodense to skeletal muscle.

May have aneurysmal dilatation of involved bowel.

Less likely obstructive and longer segment involvement compared to colonic adenocarcinoma.

Located near ileocecal valve.

GI lymphoma: Most common in stomach, followed by small bowel (ileum, jejunum, duodenum), least common site colorectal.

Splenomegaly and severe lymphadenopathy favor lymphoma but may not be present.
