Abstract


When approaching a case with a situs abnormality, using the proper terminology, making a specific diagnosis, and understanding the other often associated abnormalities that need to be excluded are of great importance. We present a case of situs ambiguous in the presence of intestinal nonrotation and an obstructing duodenal web. Our patient initially presented at two days old with bilious emesis and failure to pass meconium after birth. An abdominal radiograph demonstrated an unusual bowel gas pattern, a reversed "double bubble" sign. A subsequent thorough imaging survey was crucial to further characterize our patient's unique anatomy.  Overall, our case demonstrates many of the unusual plain radiographic and sonographic findings associated with our patient's situs abnormality and allows for review of situs abnormalities and their significance.
