Macey And Mackenzie Garrison, Conjoined Twins

- Omphalo-Ischiopagus: Fused in a similar fashion as ischiopagus twins, but facing each other with a joined abdomen akin to omphalopagus. These twins have four arms, and two, three, or four legs.
- Parapagus: Fused side-by-side with a shared pelvis. Twins that are dithoracic parapagus are fused at the abdomen and pelvis, but not the thorax. Twins that are diprosopic parapagus have one trunk and one head with two faces. Twins that are dicephalic parapagus have one trunk and two heads, and two (dibrachius), three (tribrachius), or four (tetrabrachius) arms.
- Craniopagus parasiticus: Like craniopagus, but with a second bodiless head attached to the dominant head.
- Pygopagus (Iliopagus): Two bodies joined back-to-back at the buttocks.
