Partial facial duplication (diprosopus) in a goat kid.
The anatomical and clinical features of a live-born diprosopic goat kid are described. The kid had two faces with two eyes each, two complete oral cavities and nostrils and two ears. Caudal to the neck, the kid grossly appeared normal. Both mouths of the kid showed synchronous suckling motions. Elevated respiratory and heart rates were recorded and the temperature was subnormal. Radiological examination showed a single trunk and vertebral column, normal limbs, two sets of jaws, three orbits, and contrast radiography revealed a single patent oesophagus. There was maxillary and mandibular duplication resulting in two faces. There was a cleft palate. The oropharyngeal regions of each face merged to form a single laryngopharynx and oesophagus. There was a single brain with hypoplasia of the cerebellum. The left and right cerebral hemispheres were fused rostrally, and there was duplication of the optic chiasma and the pituitary gland. The olfactory tract was absent and the superficial origins of most of the cranial nerves were not discernible.
