✦ Synopsis

The barium appearance of intraluminal duodenal diverticulum has been classically described as a "windsock" appearance. However, the CT-scan appearance of this abnormality has not been well documented. A case report of a patient with intraluminal duodenal dive&c&m is presented. The authors believe the CT-scan findings in the patient are virtually pathognomonic for this lesion and propose the term "halo" sign be applied to this previously undescribed finding.
