Epigastric heteropagus conjoined twins

Epigastric heteropagus conjoined twins: two case studies and associated DNA analysis

Conjoined twins are rarely observed, but heteropagus conjoined twins occur even less frequently. Heteropagus conjoined twins are asymmetrically conjoined twins, in which one twin is nearly anatomically normal (autosite), and the other twin remains anatomically incomplete (parasite) but physically attached to the autosite. Epigastric heteropagus conjoined twins (EHTs), referring to a parasitic t...

Epigastric Heteropagus Twin

Parasitic twining is a rare type of monozygotic monochorionic monoamniotic asymmetrical conjoined twin. We report a case of epigastric heteropagus twin. An ultrasound scan showed a defect of 1.5 cm in the epigastrium. CT showed soft tissue lobulated mass with fat and air components coming out of the epigastric defect. At operation rudimentary alimentary canal with no viscera, was found in the p...

An unusual case of monozygotic epigastric heteropagus twinning.

Epigastric heteropagus refers to unequal and asymmetric conjoined twins in which the dependent component (parasite) is smaller and usually attached to the epigastrium of the dominant component (autosite). Epigastric heteropagus is a very rare type of conjoined twins. It is generally assumed that conjoined twins represent a form of monozygotic twinning, but there has been no confirmation of this...

Conjoined Twins

Conjoined twins are twins whose bodies are anatomically joined in utero. The degree to which the twins are attached can range from simple, involving skin and cartilage, to complex, including fusion of the skull(s), brain(s), or other vital organs. There are more than a dozen classifications of conjoined twins [3] but what they all tend to have in common is the sharing of the chorion [4], placen...
