Conjoined twins are a rare occurrence without genetic predisposition. Abstract. Because sharing of organs and vascular connections between autosite and parasite of heteropagus pairs tend to be less extensive, preoperative imaging used has been more limited. Computed tomography (CT), ultrasound, and magnetic resonance imaging (MRI) are the most common initial studies in all types of heteropagus twins. Six new cases along with a systematic review are described. Conclusion: This is the first reported case of heteropagus twins with co-existing hepatobiliary and gastrointestinal continuity. The heteropagus (parasitic) variant, in which there is a fully functioning autosite and a partially formed parasite, is even more rare.

Scientists think fusion might also explain external heteropagus twins [20], where one depends on the other for survival. Parasitic and asymmetric conjoined twins are rarer anomalies of monochorionic monoamniotic twins; which consist of an incomplete twin attached to the fully developed body of the co-twin. Pre-operative workup was in progress when the twins passed Six cases of HT managed at two tertiary care teaching hospitals over the last 26 years are described. This is further supported by the fact that most conjoined twins are attached at the chest and share a heart one of the last organs to develop [19].
