Background: An adult female goat with rare malformations,
which consisted of duplication of the intestinal, lower urinary, and
genital tracts as well a pair of parasitic appendages, is presented.
Methods: A complete dissection was performed on a moribund female
goat (Capra hircus).
Results: The animal had a normal body with a parasitic attachment
located within the pelvic region. This attachment was represented by an
ovoid, trunk-like, adipose mass that lacked internal organs or vertebrae
but that had two fairly well-developed limbs with the normal components
of hind limbs. There was duplication involving the external and internal
genitalia, the urethra, the urinary bladder, and portions of the small
intestine as well as the large bowel, including the anal openings.
Conclusions: An autosite with a duplication involving the hindgut and
paramesonephric anlages was identified. These features were compatible
with life in utero and postutero and emanated from incomplete twinning
(heteropagus twins).Areview of the literature also suggests that heteropagus
twins are a very rare abnormality in both domestic animals and
humans. Anat. Rec. 247:432–438, 1997 r 1997 Wiley-Liss, Inc.
