Morphology of a six-legged goat with duplication of the intestinal, lower urinary, and genital tracts

Abstract

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). A review of the literature also suggests that heteropagus twins are a very rare abnormality in both domestic animals and humans.

Multiple Cystic Intestinal Duplications in a Cat

“…2,5,9 Documented cases in animals cover dogs, a cat, foals, and goats. 3,4,[6][7][8] Their localization in the alimentary tract and their inner lining may differ widely, and diverse theories in terms of their formation during embryogenesis have been discussed. 5 Here, we describe the first case of multiple intestinal duplications in the jejunum of a cat.…”

Subclinical intestinal duplication in a cat

“…Intestinal duplications are rare congenital anomalies that have been reported in people, dogs, cats, horses, cattle, and goats (Ablin et al 1991, Gaughan et al 1992, Otiang'a-owiti et al 1997, Stern and Warner 2000). They can occur anywhere along the gastrointestinal (GI) tract from the tongue to the rectum (Stern and Warner 2000).…”

Pathology in Practice

“…[1][2][3][4][5][6][7][8][9][10][11][12] Typically, duplication cysts consist of a blind pouch or cyst attached to the alimentary tract. [1][2][3][4][5][6][7][8][9][10][11][12] Typically, duplication cysts consist of a blind pouch or cyst attached to the alimentary tract.…”
