The result is one dominant twin with extra body parts belonging to the vestigial twin. It is also possible for tail-like tissue to form around the sacrum. [2] One theory proposes that the usage of teratogenic drugs by the mother may be a factor in the development of vestigial parasitic twins. The cause for vestigial twins is still unclear. [4]
