Postnatal image of the dicephalus tetrabrachius-dipus twin (A).
Radiographic evaluation showing vertebral spines fusion at the L4 level and a single
pelvis. A diaphragmatic hernia is observed in the fetus at right (there is evidence
of the presence of bowel loops within the thoracic cavity), without identification of
the heart and airways (B).
