Abstract
Conjoined twins are rare congenital malformations that have been reported in mammals. Two different cases are presented in this study. Case No. 1 features monocephalic, thoracopagus-conjoined twin piglets with anencephaly and palatoschisis of the Pietrain breed, and case No. 2 features monocephalic, thoracopagus conjoined twin piglets with palatoschisis and bifid root tongue of a mixed breed. These cases were examined using post-mortem and computed tomography (CT) examinations. In both cases, the conjoined symmetrical twins had a single head, one neck, and fused thoracic cavities, while the abdominal cavities were separated. Similarly, in both cases, they had four forelimbs and four hindlimbs and duplicated foramen magnum. During CT examination, in case No. 1, severe abnormalities were observed in the skull and vertebral column. In the left twin, occult dysraphism was seen from the C2 vertebra until the end of the vertebral column, and in the right twin, from the C3 vertebra until the end of the state vertebral level. In case No. 2, the oral cavity contained a tongue with a bifid root connected with one hyoid bone, and the soft palate presented a small cleft. During CT examination, the parietal bone and the occipital bones were partially duplicated. This case also presented occult dysraphism, but only in the cervical vertebrae, C1-C6 for the left twin and C1-C5 for the right twin. In both cases, abnormalities of the internal organs were revealed during necropsy. Conjoined twins with multiple congenital anomalies presented here enhance our understanding of the various clinical forms of conjoined cases in veterinary medicine.

Abstract
Craniofacial duplication abnormity is a rare phenomenon in buiatric practice. This report attends to a male German Holstein calf which could be classified as a diprosopic iniodymus. A fetus exhibiting a doubled face was delivered after fetotomy. To our knowledge, this is the first description of diprosopiasis with two cranial cavities as well as two separate encephala in a calf showing the potential extent of duplication. Throughout this work also the question is answered of whether this malformation in a bovine species arose from one embryo or rather, there is a dizygotic background by genotyping of tissue samples from both parts of the diprosopus. Regarding etiology, not only hereditary dispositions including among others a failed function of the signaling molecule Sonic hedgehog mediating regulation of craniofacial morphogenesis, but also incompletely separated monozygotic twins are discussed.
