Occipitoatlantoaxial malformation in an adult goat.
An occipitoatlantoaxial malformation was diagnosed in a 1-year-old Murciano-Granadina goat. At clinical examination, the head and cranial part of the neck were deviated to the right. Clinical signs of spinal cord or brain disease were not observed. At necropsy, morphological abnormalities were seen in the craniovertebral junction and cervical vertebrae, characterized by a firm attachment and incomplete articulation between the occipital bone and the atlas, and scoliosis in the cervical regions. The definitive diagnosis was bilateral asymmetrical occipitoatlantoaxial fusion with rotation of the atlas and atlantoaxial subluxation. To the authors' knowledge, this case report is the second occipitoatlantoaxial malformation described in a goat and the first description in an adult goat.
