Table 1. Patient symptoms, CT imaging findings and pathology in seven children with EC.

Patient	Age (years)	Gender	Symptoms	CT colonic findings	Other CT findings	Pathology
1	16	F	Rectal bleeding, abdominal pain	Focal cecal haustral thickening		Normal terminal ileum, 90 eosinophils/high-power field in cecum/ascending colon, 40 eosinophils/high-power field in transverse colon/sigmoid. Rectal crypt abscesses and cryptitis
2	1.3	F	Weight loss, fevers, abdominal pain, diarrhea, emesis, peripheral edema	Normal. No colonic contrast		Increased lymphoid follicles, 60 eosinophils/high-power field, fibrosis
3	12	F	Abdominal pain, anorexia, diarrhea	Cecal wall hyperenhancement. No colonic contrast	Mild segmental duodenal and jejunal wall thickening	Severe colitis, cryptitis, crypt abscess, mixed inflammatory infiltrate of eosinophils, plasma, and lymphocytes
4	2.4	M	Shock, rectal bleeding	Extensive colonic wall thickening. Extensive pneumatosis from the rectum to ascending colon, most prominent in the rectum	Moderate terminal ileal wall thickening. Moderate ascites. Moderate bilateral pleural effusion	Poorly formed granuloma, 50–80 eosinophils/highpower field, acute rectal cryptitis and crypt abscesses
5	10	M	Abdominal pain, bloody diarrhea	Extensive colonic wall thickening – most severe in the cecum and ascending colon, extending to the descending colon/sigmoid junction	Mild diffuse mesenteric lymphadenopathy. Small volume of ascites in the pelvis	Significant eosinophil degranulation, 40–100 eosinophils/high-power field, invading crypts, lamina propria mixed inflammation
6	13	M	Rectal bleeding, abdominal pain, peripheral edema	Extensive colonic wall thickening, greatest in ascending colon (marked) with downstream involve ment to the mid-sigmoid, focal region in the trans verse colon, sparing of the hepatic flexure	Mild terminal ileal wall thickening. Small volume of ascites inferior to liver. Moderately enlarged right lower quadrant mesenteric lymphadenopathy	Positive sigmoid granuloma, 50–75 eosinophils/high-power field, chronic active colitis, cryptitis with mixed inflammatory cells
7	16	M	Abdominal pain, bloody diarrhea	Focal cecal haustral thickening	Mild right lower quadrant mesenteric lymphadenopathy	Severe chronic active colitis, single granuloma, increased eosinophils in lamina propria
