Persistent cloaca, fused kidneys, female pseudohermaphroditism and skeletal anomalies in a simmental calf.

A 5-day-old Simmental calf was referred to our department for atresia ani and postural abnormalities caused by skeletal deformities. The calf had a short and deviated tail and a bowed hind limb. The calf appeared like a male because of the prepuce and penis located just near the teats and the absence of female external genitalia. During the necropsy, a horseshoe kidney, single ureter that originated from the kidney, and bilateral uterine horns with one ovary each were detected. The ureter, blind-ended large intestine, and bilateral uterine horns were connected to a dilated cloaca having two sacs, which were filled with a yellowish brown viscous fluid admixed with meconium and urine. Skeletal deformities found included scoliosis, partial synostosis of vertebrae, deviation of rudimentary sacrum and coccygeal vertebrae, and narrowed pelvic cavity. This is the first report of an anomalous combination including urogenital, large intestinal, and skeletal deformities in cattle.
