Annular Pancreas

Annular pancreas is the second most common congenital anomaly of the pancreas and occurs when the two pancreatic anlagen fuse too early. On cholangiography, CT, ultrasound, and MRI, this condition may be di agnosed when pancreatic tissue is noted surrounding the descending duodenum89-92 (Figs. 2-49 and 2-50). It may even be clearly indicated on plain films (Fig. 2-51). This condition may cause symptomatic duodenal stenosis in the neonate. A less symptomatic or asymptomatic clinical presentation can be encountered in older children and adults. This anomaly is often associated with duodenal atresia, pancreas divisum, or esophageal atresia.
