Abstract

Introduction: Annular pancreas is a rare developmental anomaly, representing 1% of the neonatal intestinal obstructions.

Case Report: We report a case of prenatal sonographic diagnosis of duodenal obstruction, observed on the 32nd gestational week. There was no other ultrasound finding beyond the ‘double bubble’ sign, which persisted until labour, by the 39th week. An annular pancreas was diagnosed at the 3rd day of life, by an exploratory laparotomy.

Conclusion: Diagnosis of partial or total duodenal obstruction is almost exclusively suggested by the ‘double bubble‘ sign, resulting from a dilatation of the stomach and duodenum. Despite being a rare anomaly, the differential diagnosis of annular pancreas should be considered, if this prenatal sonographic finding is observed.
