What is the first radiographic study that is performed in symptomatic patients with previously diagnosed Crohns disease?
CT is performed first, primarily to exclude an intra-abdominal abscess and to show the cause of separated bowel loops—whether abscess, inflammation, or fibrofatty proliferation. Fat does not creep or proliferate, so “fibrofatty proliferation” is a misnomer. Prominent fat may be related to retraction of fat secondary to inflammation spreading along lymphatic and venous channels.
