A 2-year-old neutered female Scottish Fold cat was presented with an 8-week history of progressive back pain, paraparesis and decrease of postural reactions in both pelvic limbs. MRI showed spinal cord compression from both ventral sides, which originated from the T4 vertebral body and pedicle. The lesion compressing the spinal cord had a bone-like density on CT, and endoscopic surgery was performed to excise it. Histopathological examination of the resected tissue showed no evidence of malignancy and the lesion was diagnosed as vertebral hypertrophy. After surgery, the neurological status of the cat gradually improved. The cat was ambulant at the follow-up evaluation 2 weeks after surgery. Six months later, hindlimb paresis had improved considerably, and no recurrence was observed on CT.
This is the first description of thoracic vertebral canal stenosis due to hypertrophy of a single vertebra in a young cat. Excision of the hypertrophic vertebra by endoscopic surgery is less invasive than open surgery and may give a good prognosis.
一只2岁已绝育的雌性苏格兰折耳猫，出现进行性背痛、双后肢轻瘫及姿势反射减弱8周。磁共振成像（MRI）显示脊髓腹侧受压，起源于第4胸椎椎体和椎弓根。CT显示压迫脊髓的病变呈骨样密度，遂行内镜手术切除。切除组织的组织病理学检查未发现恶性证据，病变诊断为椎体肥大。术后，猫的神经状态逐渐改善。术后2周随访评估时猫可行走。6个月后，后肢轻瘫明显改善，CT未观察到复发。
这是首次报道幼猫因单个椎体肥大导致胸段椎管狭窄。与开放手术相比，内镜手术切除肥大椎体的侵入性较小，且可能预后良好。
