Case Report: Cat Scratch Colon in a Young Patient

A Watson et al. JPGN 2024;79:1081–1083. Cat scratch colon in a patient with very early-onset Crohn’s disease with diverting ileostomy

Case report: This image is from the ascending colon of a 12 yo with Crohn’s disease sp diverting ileostomy.

“Cat scratch colon refers to the rare endoscopic finding of erythematous linear breaks that arise spontaneously, typically in the ascending colon and/or cecum, resembling scratches made by a cat, on otherwise unremarkable mucosa…It is presumed to be a benign condition likely caused by barotrauma from air insufflation during colonoscopy in a colon with altered elasticity or when the rate of insufflation exceeds the rate of air passage, such as in a diverted colon.23

My take: Surprisingly, the cat scratch colon finding is not consequential.
