The objective of this study was to describe the clinical signs, neurologic examination findings, diagnostic imaging results, and pathologic diagnosis of ossifying fibroma in the cervical vertebra of a dog. A 3-year-old spayed female Pembroke Welsh corgi dog exhibited severe cervical pain and left-sided postural reaction deficits. Magnetic resonance imaging (MRI) revealed a lobulated contrast enhancing mass associated with the C6 cervical vertebra. Due to the lack of response to pain medications, humane euthanasia was elected, and histopathologic evaluation of the mass revealed a fibro-osseous lesion most consistent with an ossifying fibroma. This neoplasm is most commonly associated with the mandible of young horses and has not been previously reported in vertebrae in veterinary medicine. Key clinical message: This case is the first report of a fibro-osseous lesion most consistent with an ossifying fibroma affecting a vertebra in veterinary medicine.
本研究旨在描述一例犬颈椎骨化纤维瘤的临床症状、神经学检查结果、诊断影像学结果和病理学诊断。一只 3 岁已绝育雌性彭布罗克威尔士柯基犬表现出严重的颈部疼痛和左侧姿势反应缺陷。磁共振成像（MRI）显示与 C6 颈椎相关的分叶状增强肿块。由于对疼痛药物治疗无反应，选择了安乐死，对肿块的组织病理学评估显示出纤维骨性病变，最符合骨化纤维瘤。这种肿瘤最常与幼年马的下颌骨有关，以前在兽医的椎骨中尚未报道过。关键临床信息：本病例是首例兽医报道的最符合骨化纤维瘤的纤维骨性病变影响椎骨。
