A 47-year-old male with stricturing Crohn’s disease (CD) presented with intermittent right-lower-quadrant abdominal pain (RLQAP), nausea/vomiting, and constipation.
His history revealed small bowel resections (age 20/32 years) followed by 9 years of symptomatic remission with sulfasalazine, which was discontinued 7 years ago (medical insurance lapse). For 6 years, he had mild, intermittent, self-resolving RLQAP with nausea/vomiting that became more frequent two months ago, necessitating two hospitalizations (unremarkable esophagogastroduodenoscopy, colonoscopy, barium enema).
On presentation, he had mild RLQAP and tenderness without rebound/distention. Magnetic resonance enterography showed a 4-cm-dilated distal ileum (
Figure A, asterisk), with 3 × 0.6-cm stricture proximal to the ileocecal valve (
Figure A, arrow). Ileocecectomy revealed prominent adipose tissue in the submucosa between the mucosa and muscularis propria (
Figure B, right brace) and dilated lymphatic vessels in the terminal ileum (
Figure C, arrows) without evidence of CD.
This is the first case of lipohyperplasia causing small bowel stricture/obstruction in CD. Although management is still resection, lipohyperplasia should be considered in the differential diagnosis of small bowel stricture even in patients with known stricturing CD.
