CORRAL G, Gonzalo; LABRA W, Andrés  y  SCHIAPPACASSE F, Giancarlo. Situs Ambiguous abnormalities in adults: A study of four cases. Rev. chil. radiol. [online]. 2013, vol.19, n.1, pp.38-43. ISSN 0717-9308.

Anomalies Situs (ASIT) has been described mainly in the pediatric population and there is little information on this in adults. These are very rare abnormalities; in the case of Situs Ambiguous (SAMB) in adults, there have only been a few published case series. SAMB, also called heterotaxy or heterotaxy Syndrome, is defined as the abnormal or ambiguous positioning of organs and vessels, that could also be associated with morphological alterations characteristic of each organ. There are two main groups within SAMB: polysplenia and asplenia. This publication present a specific literature review, with emphasis on the classification of adult ASIT and abdominal findings in cases of SAMB. It will be complemented clinically and radiologically with four cases of abdominal tomographic imaging studies.

Palabras clave : Heterotaxy; Polysplenia; Situs ambiguus.
