A 6-months-old male mixed-breed dog was admitted to the veterinary hospital with lameness in the right pelvic limb, proprioceptive ataxia, and suspected spinal cord injury in the lumbosacral segment. Upon palpation, firm nodules were noted on the bony surface of the thoracic and pelvic limbs, ribs, vertebrae, and tail. The radiographic study showed nodules of low radiopacity with well-defined limits and smooth contours, one of which was overlapping the fifth lumbar vertebra. Given the clinical presentation indicative of spinal cord injury, the animal was subjected to hemilaminectomy for nodular resection. Histopathological examination of the biopsy enabled the diagnosis of osteochondroma. The clinical follow up after surgery showed improvement in walking, despite persistent monoparesis in the right pelvic limb. The radiographic study in association with clinical and histopathological exams allowed the diagnosis and monitoring of the lesions.
一只 6 月龄的雄性混血犬因右骨盆肢体跛行、本体感觉共济失调和疑似腰骶段脊髓损伤而被送诊至兽医医院。触诊时，发现其胸、四肢、肋骨、脊柱和尾巴的骨表面有坚硬的结节。放射学研究显示，结节的放射不透明度较低，边界清晰，轮廓光滑，其中一个结节与第五腰椎重叠。鉴于提示脊髓损伤的临床症状，对该动物进行了半椎板切除术以切除结节。活检的组织病理学检查可确诊为骨软骨瘤。手术后的临床随访显示，尽管右骨盆肢体仍持续出现单瘫，但行走能力有所改善。放射学研究结合临床和组织病理学检查可用于诊断和监测病变。
