To describe the clinical and imaging findings of 33 dogs with discospondylitis (BDS).
33 client owned dogs from four veterinary specialty hospitals within Colorado and Arizona with at least one positive test and spinal diagnostic imaging.
Retrospective review of signalment, physical and neurological examination findings, laboratory results, serology, and diagnostic imaging of 33 dogs with BDS. All imaging was reviewed by a board-certified veterinary neurologist. Radiographs were reviewed by a board-certified veterinary radiologist blinded to MRI and CT findings.
31/33 (94%) dogs were <5 years old (median = 2.5 years, mean = 2.9 years, range 0.5-10 years). 21/29 (72%) dogs had signs of nonspecific pain, spinal pain, or lameness for >3 months (median = 6 months, mean = 8.2 months, range 5 days-4 years). Fever was seen in only 4/28 (14%) dogs. Multifocal lesions were evident on radiographs in 21/29 (72%) dogs and MRI in 12/18 (67%) dogs. Smooth, round, central end-plate lysis, defined as "hole punch" lesions, were identified radiographically in 25/29 (86%) dogs. Vertebral physitis or spondylitis without discitis was evident on MRI in 7/18 (39%) dogs.
Dogs with BDS typically present at a young age with a long duration of clinical signs. Identification of radiographic "hole punch" lesions and MRI evidence of vertebral physitis, spondylitis, and paravertebral inflammation without discitis should increase suspicion for BDS. BDS may be increasing in frequency in the southwestern United States, and dogs with signs of chronic spinal pain and/or lameness should be screened for .
描述33只患有椎间盘脊椎炎（BDS）犬的临床和影像学表现。
来自科罗拉多州和亚利桑那州四家兽医专科医院的33只客户拥有的犬，至少有一项阳性检测结果并进行了脊柱诊断性影像学检查。
对33只患有BDS的犬的信号、体格和神经学检查结果、实验室检查结果、血清学检查以及诊断性影像学检查进行回顾性分析。所有影像学检查均由一名获得委员会认证的兽医神经科医生进行评估。X线片由一名对MRI和CT检查结果不知情的获得委员会认证的兽医放射科医生进行评估。
33只犬中有31只（94%）年龄小于5岁（中位数=2.5岁，平均数=2.9岁，范围0.5 - 10岁）。29只犬中有21只（72%）出现非特异性疼痛、脊柱疼痛或跛行症状超过3个月（中位数=6个月，平均数=8.2个月，范围5天至4年）。仅4只（14%）犬出现发热。29只犬中有21只（72%）在X线片上可见多灶性病变，18只犬中有12只（67%）在MRI上可见多灶性病变。29只犬中有25只（86%）在X线片上可见光滑、圆形、中央终板溶解，定义为“打孔”病变。18只犬中有7只（39%）在MRI上可见椎体骨炎或脊柱炎但无椎间盘炎。
患有BDS的犬通常发病年龄较轻，临床症状持续时间较长。识别X线片上的“打孔”病变以及MRI上椎体骨炎、脊柱炎和无椎间盘炎的椎旁炎症证据应增加对BDS的怀疑。在美国西南部，BDS的发病率可能在上升，对于有慢性脊柱疼痛和/或跛行症状的犬应进行筛查。
