Half annular pancreas - a cadaveric case report

Background: Annular pancreas is an unusual and not often reported congenital anomaly of the pancreas. Thus, it is rarely suspected when the patient is asymptomatic. However, the condition may be occasionally associated with other clinical complications of the abdomen. Case Presentation: We report here a case of partial or incomplete annular pancreas detected during cadaveric dissection. A triangular projection from the head of the pancreas extended over the anterior surface of the second part of the duodenum and covered its major portion. As a possible compression effect, the first part of the duodenum was dilated. Conclusion: Prior knowledge of existence of incomplete annular pancreas helps in the diagnostic approach of radiological procedures. As annular pancreas may predispose to other congenital or morphological abnormalities, its timely diagnosis is warranted.
