Epigastric Heteropagus Conjoined Twins

Area of Science:

• Medical Science
• Genetics
• Embryology

Background:

• Heteropagus twins, also known as parasitic twins, are a rare form of conjoined twins.
• They arise from a single zygote, resulting in monochorial, monoamniotic gestation.
• Incidence is less than 1 in 1,000,000 live births.

Observation:

• A rare case of epigastric heteropagus twins was observed.
• The parasitic twin was attached to the autosite in the epigastric region.
• The parasite exhibited a fully formed pelvis, lower and upper limbs, and male genitalia.

Findings:

• The conjoined twins presented with a large omphalocoele.
• This case represents an extreme example of asymmetrical conjoined twinning.
• Detailed anatomical features of the parasitic twin were documented.

Implications:

• This case contributes to the understanding of rare congenital anomalies in twin pregnancies.
• Further research into the genetic and developmental factors of heteropagus twins is warranted.
• Clinical management strategies for such rare conditions may benefit from this case study.
