Ischemic colitis (IC) appears differently in computed tomography scans relative to the slice axis, including target sign on cross section, and the accordion sign in longitudinal image. The Mercedes-Benz sign is originally a triradiate radiolucent shadow, representing gas accumulation within a gallstone. The Mercedes-Benz sign of IC, which we call, is presented by hyperemic mucosa and the triradiate form is produced presumably by tenia coli. We present a case of IC, presenting this interesting radiological finding. Although nonspecific, this sign may allow us to predict the presence of IC.
