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 diverticulum 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.
十二指肠腔内憩室的钡剂表现传统上被描述为“风袋”样表现。然而，这种异常的CT扫描表现尚未得到充分记录。本文报道了一例十二指肠腔内憩室患者。作者认为该患者的CT扫描表现实际上对此病变具有诊断意义，并建议将“晕”征这一术语应用于这一先前未描述的表现。
