Abstract
Myelo-computed tomography of a paraparetic 14-year-old dog revealed subarachnoid distension with an intradural filling defect above the T13-L1 disc space. T12-L1 hemilaminectomy followed by durotomy allowed removal of a large piece of degenerated disc material that compressed the spinal parenchyma. Full return to function was achieved 10 days post-surgery. The distension was likely secondary to the intradural herniation, and is a rare and distinct finding.
摘要
对一只截瘫的14岁犬进行脊髓计算机断层扫描显示，在胸13-腰1椎间盘间隙上方存在蛛网膜下腔扩张，并伴有硬膜内充盈缺损。随后进行胸12-腰1半椎板切除术及硬脊膜切开术，成功移除了一大块压迫脊髓实质的退变椎间盘组织。术后10天功能完全恢复。这种扩张可能继发于硬膜内疝，是一种罕见且独特的发现。
