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

Conjoined twins, though uncommon, continue to present some of the most chal lenging questions for current diagnosis and therapy. The myriad of presenta tions demands a thorough multisystemic imaging evaluation before fully info rmed therapeutic and ethical decisions can be made. We present an unusual c ase 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 sonic other imaging tests and can complement those other tests that re main necessary. We would suggest that when a CT examination is considered t o evaluate this condition, an imaging interpretation that is independent of acquisition plane and that has multisystem versatility should be considere d.
