Case Review: CT & PET of Colonic Lymphoma - a podcast by Daniel J. Kowal, MD

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.
