Polysplenia syndrome with situs ambiguous, common mesentery, and IVC interruption discovered incidentally in an adult.

Polysplenia syndrome associates multiple spleens to other malformations, most frequently cardiac, vascular, visceral, and biliary malformations. Polysplenia has been described mainly in childhood owing to critical anatomic malformations related to cardiac defects or biliary atresia. We present a case of polysplenia syndrome found in a 58-year-old man. Only those with mild anatomical abnormalities reach adulthood without a diagnosis. Radiological examinations are helpful to the diagnosis by ascertaining the location and number of spleens, location of other organs in the chest and abdomen, and identification of other associated anomalies.
