Complete dipygus is a very rare congenital malformation involving complete lumbosacral duplication with two pelves and four lower limbs [1]. Several incomplete forms have been reported. Pygomelia is an incomplete form in which two of the lower limbs fusion (symmelia) form a single supernumerary middle limb inserting into the pelvis [2—5]. Pygomelia has often been described as caudal or lumbosac...

Dipygus is a teratological fetus with a double pelvis, genitals, and extremities. Congenital duplications in cattle are rare. Caudal duplication is more common in sheep and pigs while cranial duplications seem to be predominant in cattle. Asymmetric or parasitic conjoined twins consisting of an incomplete twin (parasite) attached to the body of a fully-developed twin (autosite). This report dea...

Caudal duplication is a rare anomaly with less than 30 reported cases. For those patients who also have double bladders, there are not enough data regarding the function of the lower urinary tract. A boy with caudal duplication anomaly was evaluated fluoroscopically and urodynamically. The results of the evaluation showed that the bladders were filling and emptying synchronously with normal and...

Caudal duplication (dipygus) is an uncommon pathologic of conjoined twinning. The conjoined malformation is classified according to the nature and site of the union. We report the presence of this malformation in a female crossbreed puppy. The puppy was delivered by caesarean section following a prolonged period of dystocia. External findings showed a single head (monocephalus) and a normal cra...
