An 8 yr old female spayed golden retriever presented for a 3 wk history of progressive pelvic limb ataxia. MRI revealed a well-circumscribed T2-weighted hyperintense, T1-weighted poorly contrast-enhancing extradural mass to the right of the spinal cord at the level of L1 causing severe spinal cord compression. A right-sided hemilaminectomy was performed to remove the mass, and histopathology revealed an intraosseous keratinized cyst. A complete neurologic recovery was made within 2 wk following the surgery. This case illustrates a rare diagnosis and the first case report describing MRI findings and favorable clinical outcome after surgical management of a spinal intraosseous keratinized cyst.
一只 8 岁雌性已绝育的金毛猎犬出现了 3 周的进行性骨盆肢共济失调病史。MRI 显示在 L1 水平脊髓右侧有一个边界清楚的 T2 加权高信号、T1 加权低对比增强的硬膜外肿块，导致严重的脊髓压迫。进行了右侧半椎板切除术以切除肿块，组织病理学显示为骨内角化囊肿。手术后 2 周内完全恢复神经功能。本病例说明了一种罕见的诊断，也是首例描述 MRI 发现和手术治疗后良好的临床结果的病例报告。
