Case Report Congenital intestinal polyp associated with intussusception in a 3-day-old foal

Hyperplastic or adenomatous polyps have been previously described in both human medicine and domestic species (Crawford 1999). This condition has been most frequently reported in cats (Orr et al. 1980) and also in dogs and sheep (Barker et al. 1993). To date, only one report of an adenomatous polyp in the equine species exists (Patterson-Kane et al. 2000). To the authors’ knowledge, an intussusception secondary to a hyperplastic polyp has not been reported previously in an equine neonate. The case reported here describes the finding of a congenital polyp post mortem in a neonatal foal and the history leading to euthanasia.
