Chronic Active Epstein-Barr Virus-Associated Enteritis: CT Findings and Clinical Manifestation

Table 4

Comparison of CTE features between CAEAE and IBD.

	Main involved location	Pattern of mural thickening	Length of involvement	Pattern of attenuation	Perienteric abnormalities
CAEAE^a	All segmental colons may be involved	Asymmetric thickening	Segmental involvement	Layered attenuation	Fat stranding, adenopathy
CD^b	Terminal ileum, ascending colon	Asymmetric thickening	Focal involvement	Layered or white attenuation (acute, active disease), grey attenuation (chronic disease)	Fat stranding, adenopathy, prominent vasa recta, fistulas and abscesses
UC^b	Rectum, descending colon	Symmetric thickening	Segmental or diffuse involvement	Layered attenuation	Not common
