Conjoined twins: Allison and Amelia
Eight-month-olds Allison June and Amelia Lee Tucker were joined at the lower chest and abdomen. The two sisters shared a chest wall, diaphragm, pericardium and liver.
The two girls have an omphalopagus connection, which accounts for 33 percent of all conjoined twins, according to the University of Maryland Medical Center.Credit: The Children's Hospital of Philadelphia video
