title: Small bowel CT fat density target sign in chronic radiation enteritis.
abstract: On CT, a thickened intestinal wall configured with a middle layer of low attenuation surrounded on each side by layers of higher attenuation has been termed the target sign. The presence of fat within the submucosal layer of the small intestine is a well-known manifestation of Crohn's disease, but has not been reported in other chronic intestinal diseases. We describe CT findings of fat density target sign in a patient with prior radiation.
