Imaging Diagnosis of Annular Pancreas in Newborn / 实用放射学杂志

ABSTRACT

Objective To evaluate the imaging findings of the annular pancreas in newborn and the diagnostic value.Methods Clinical data,X-ray and CT features of annular pancreas in 7 cases of newborn were retrospectively analyzed,and 6 cases were confirmed by operations.Results Abdominal erect position plain films were performed in six patients and showed typical "double bubble sign" without distal gas in 5 cases,with a little gas in 1 case.Seven patients underwent upper gastrointestinal contrast studies and showed stenosis of the descending duodenum like "the thin striation",and contrast agent passed with difficulty.There were soft tissue shadows encircling the descending duodenum in 4 cases on CT plain scans,in which 3 cases showed stenosis of the descending duodenum like "the mouse tail",and the soft tissue shadows obviously enhanced the same as enhanced pancreas on contrast-enhanced CT scans.Conclusion The annular pancreas in newborn are of characteristics at imageology.
