Antenatal Diagnosis of Complete Annular Pancreas With Postnatal Surgical Follow-Up: A Case Report

Annular pancreas is a rare congenital disorder, which is characterized by partial or complete pancreatic tissue surrounding the second part of the duodenum. It can be diagnosed antenatally on ultrasound. We are reporting a case where a double bubble sign on an antenatal scan was seen, which was followed up after the delivery of the baby, and radiography also confirmed the findings. Both investigations suggested duodenal obstruction (duodenal atresia and annular pancreas were kept as possible causes). The child was taken for surgery and pancreatic tissue surrounding the second part of the duodenum was seen, confirming the diagnosis of annular pancreas.
