Abstract |
A 20-day-old female Diprosopia in Holstein calf was observsd macroscopically and radiographically. Anterior head duplication(Diprosopia) was observed and all structures caudal to it were normal. She had two muzzles, three eyes, two ears and two tongues. The tongues were joined at their base just posterior and had one hyoid bone. Schistognathia and cleft lips were also observed in the lower jaws. She had an oral cavity, single epiglottis and a laryngeal cavity communicated with one trachea. The cerebral hemispheres were duplicated and fused together in the caudal region. The olfactory and optic nerves were duplicated. The incisive, nasal, pterygoid, parietal, ethmoid bones and vomer were duplicated, respectively. The skull of Diprosopia was shared by an occipital bone. The mandibules, palatines and sphenoid bones were duplicated incompletely. Three orbits and two fontanelles were observed. The medial lacrimal bones and maxillae were duplicated incompletely and fused with each other, respectively. Cleft palates were observed. Medial mandibular mass which was fused together and was duplicated incompletely at the part of its cranial, was shown synchondrosis with the left mandible, but not with the right. |
