Abdominal pain. Assess Crohn's disease activity. ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Left renal subcentimeter simple cyst.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is a severe circumferential wall thickening and surrounding inflammation of the terminal ileum and mild wall thickening of the cecum which is conical in configuration. Proximal to the very distal terminal ileum the bowel is focally dilated up to 3.0 cm (series 5 image 26). Proximal to this the bowel is mildly thickened and narrowed for a 3.8 cm length segment of distal ileum. The more proximal bowel is normal in caliber. There is marked postcontrast enhancement of the described thickened bowel and surrounding soft tissue with restricted diffusion of the bowel. No discrete fluid collection to suggest an abscess.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: See above discussion.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Active phlegmonous inflammation of the terminal ileum and cecum. Mild proximal short segment bowel dilatation of the terminal ileum. More proximal 3.8 cm focal stricture of the distal ileum without significant proximal dilatation.
