Omphalopagus parasitic twin: A case report and literature review

Parasitic conjoined twins arise from the embryonic death of one twin, whose body parts remain vascularized and attached to the primary twin. Parasitic twins are rare and present unique challenges regarding the location of their attachment to the autosite and shared organs. In this case report, we describe the presentation and treatment of a parasitic omphalopagus twin that shared its liver with the autosite left liver lobe. The condition was not recognized before delivery, most likely due to the lack of prenatal care in the remote rural area to which the patient belonged. After a vaginal delivery, the twins were referred to our tertiary center, where a successful separation of the parasitic omphalopagus twin from the autosite was achieved.
