CT appearance of the ventral pancreas

Pancreas divisum has not been previously described in the computed tomography (CT) literature of the pancreas. Nine endoscopic retrograde choledochopancreatography (ERCP) confirmed examples of pancrease divisum were evaluated by CT. Four patients (44.4%) were observed to have a characteristic lobulated appearance of the pancreatic head. Of 21 patients with a normal pancreas confirmed by ERCP, only 2 (9.5%) showed lobulation on CT. The incidence of this previously unreported configuration was found to be significantly higher (p less than 0.05) in patients with pancreas divisum than in those with normal ductal anatomy.
