[Computerized tomography findings in annular pancreas in an adult]

We present a case of annular pancreas in an adult female studied by computerized tomography. CT demonstrated an enlarged pancreatic head in the center of which was visualized the contrast-filled duodenal lumen. We consider these findings to be sufficiently characteristic of annular pancreas to permit differential diagnosis with neoplastic processes of the pancreatic head without having to resort to more invasive diagnostic methods like endoscopic retrograde cholangiography.

Cerebral computed tomography in maple syrup urine disease

Maple syrup urine disease (MSUD) is an inherited metabolic disorder due to decreased decarboxylation of branched chain keto acids triggering an accumulation of leucine, isoleucine, and valine. We describe two infants with biochemically confirmed MSUD in whom computed tomography (CT) revealed cerebral edema. In one of these cases repeat CT 40 days after institution of appropriate therapy revealed that the edema had disappeared and the ventricles had enlarged.
