Schistosomus (Fissura abdominalis), atresia ani and arthrogryposis in a Turkoman foal

Abstract

Schistosomus reflexus (SR) is a rare monstrosity primarily in cattle. This fatal congenital anomaly is characterized by defect fusion that result in abdominal and sometimes thoracic viscera exposure (schistosomus), ventral curvature of the spine and curved chest walls as lateral (reflexus). The present study describes schistosomus (Fissura abdominalis) without reflexus in a Turkoman foal. The foal exhibited rupture of abdominal wall and the internal organs were exposed and outside the body. Arthrogryposis and atresia ani were other anomalies associated with SR. The occurrence of inherited anomalies is economically considerable. To the authors’ knowledge, it seems the first report of SR with atresia ani and arthrogryposis in a foal.
