Parasitic Twins

Parasitic twins, also known as unequal conjoined twins or asymmetrical twins, are a subtype of conjoined twins that occurs when one of the twins ceases development. The parasitic twin remains partially formed and nonfunctional or is fully dependent on the dominant twin, known as the autositic twin. The most common type of parasitic twins gives the autositic twin extra limbs, appendages, or organs. However, there are other kinds of parasitic twins like dipygus parasitic twins that have duplication of legs, hands, feet, or sexual organs, and the epigastric parasite, which is an incomplete twin usually attached to the autositic twin’s abdomen.

One of the most common health complications among parasitic twins is heart failure due to the heart having to supply blood to both bodies.
