Conjoined twins: multiorgan system evaluation by multidetector CT and 3D volume rendering.

Abstract

Conjoined twins, though uncommon, continue to present some of the most challenging questions for current diagnosis and therapy. The myriad of presentations demands a thorough multisystemic imaging evaluation before fully informed therapeutic and ethical decisions can be made. We present an unusual case of asymmetric omphaloischiopagus conjoined twins who were evaluated by multidetector CT and 3D volume rendering. This single technique can provide a large amount of information from a single study that can negate the need for some other imaging tests and can complement those other tests that remain necessary. We would suggest that when a CT examination is considered to evaluate this condition, an imaging interpretation that is independent of acquisition plane and that has multisystem versatility should be considered.
