Craniothoracopagus (monocephalus dipygus tetrabrachius) in twin pigs

The objective of this study was to report a case of craniothoracopagus, monocephalus, dipygus, tetrabrachius in swine, created in anthropized areas of the Amazon forest for the implementation of livestock. During the physical examination, we observed that lesions were characterized by monocephaly and presence of a midline that became more evident in the nose region, with two snouts and four nostrils. The oral cavity was unique with total duplication of the lower jaw and tongue. The anterior region of the body had two sets of limbs (four in total), one in a normal spatial position and the second pair positioned dorsally. In the posterior region, we observed complete duplicity of the pelvis, pelvic limbs and genital organs. There are few reports on craniotoracopagus in pigs, thus it is essential to describe reports like these to collaborate with Veterinary Teratology, this being the first case to be described in the literature in Rondônia.
