“…Ischiopagus (fusion at autosite hip) twins accounted for 5 of the 39 reports, rachipagus (fusion at the spine) for 4, and craniopagus (fusion at the head) for 1. One parasite was described as acardiac acephalic, but the specific juncture site was not mentioned or depicted [56]. In 5 cases, the specific variant was not specified [13].…”

Epigastric Heteropagus Twinning is a rare congenital anomaly, constituting 1-2% cases of conjoined twins. In this type of twinning, the dependent portion (parasite) is attached to the epigastric region of the fully formed host (autosite) and derives nutrition from it. We report a case of Epigastric Heteropagus Twins born in a private nursing home in Jaipur, Rajasthan. The parasite exhibits rudimentary lower limbs and male external genitalia. It was a case of abortive twinning. The twins were separated and brought to the Department of Anatomy, SMS Medical College, Jaipur for academic interest. The blood supply of the parasite was found to be derived from falciform ligament.

“…Therefore, both sets of twins described by us are rare variants. Most cases described in the literature have quoted the attachment of the parasitic twin at the epigastric region [1][2][3][4][5][6][7][8][9][10][11][12]. The extent of the development in the parasitic twin has also varied in different case reports.…”

“…The extent of the development in the parasitic twin has also varied in different case reports. Most parasitic twins had better developed lower limbs [2,7,8,11,12], while very few have well-developed upper limbs [6,10]. This may be either because that the lower half of the body in the parasite is more resistant to resorption or the resorption process takes place in a cranio-caudal direction.…”

“…While conjoint twins have the highest incidence of being attached at the thorax (thoracopagus) [1], the literature has very few cases of thoracopagus parasitic twins [1,2]. In most of the reported cases, the parasitic twins were found to be attached at the epigastrium and frequently also had omphalocele [1][2][3][4][5][6][7][8][9][10][11][12]. We, herein, report two sets of thoracopagus parasitic twins.…”

Thoracopagus parasites in two sets of twins: evidence for the ‘fusion theory’

et al. 2008

We report two sets of parasitic twins attached in the thoracic region. Exomphalos major in the autosite was present in both cases. While in case 1, the autosite could be salvaged after easier dissection, in case 2, the autosite could not be salvaged due to the presence of the life-threatening anomalies. The presence of a right-angled communication between the gastrointestinal tracts of the autosite and the independent tactile responses of the parasite from that in the autosite supports the 'fusion theory' to explain the fusion of the embryos that could have led to this defect. The presence of the ano-rectal malformation and common bile duct dilatation exclusively in the parasite appears to be the result of the abnormalities in the endodermal-mesodermal interactions, probably due to the relative positioning of the parasite with respect to the autosite.
