The term spinal dysraphism defines an incomplete fusion or a bone defect that affects the neural structures of the spinal cord due to a neural tube malformation. A 6-month-old, male, mixed-breed dog, was evaluated for paraparesis, pelvic limb proprioceptive ataxia, faecal and urinary incontinence. A neurological examination indicated an L4-S3 spinal cord segment lesion. A thoracolumbar and lumbosacral spine magnetic resonance imaging was performed and a closed spinal dysraphism, with the presence of a lipomyelomeningocele, was detected. The magnetic resonance imaging showed an entire narrowing passage and a fibrous mass stemming from a wedge-shaped gap in the caudal region of the dorsal lamina of the L4 vertebra, leaving the spinal canal towards the skin surface in the region where the skin stigma was observed. A dorsal laminectomy was performed, the spinal cord was exposed, and the entire fibrous mass was excised. Three months postoperatively, the patient had a complete resolution of the urinary and faecal incontinence showing only a residual mild paraparesis, which remained six months after surgery. The surgical procedure resulted in the satisfactory recovery of the neurological signs.
脊柱裂这个术语定义了一种由于神经管畸形而导致的不完全融合或骨缺损，它会影响脊髓的神经结构。一只6个月大的雄性混血犬，因后肢轻瘫、骨盆肢体本体感觉共济失调、大小便失禁而接受评估。神经学检查显示L4 - S3脊髓节段有病变。进行了胸腰椎和腰骶椎磁共振成像检查，发现了闭合性脊柱裂，并伴有脂肪脊髓脊膜膨出。磁共振成像显示整个通道变窄，有一个纤维性肿块，起源于L4椎骨背侧椎板尾端的楔形间隙，在观察到皮肤印记的区域从脊髓腔通向皮肤表面。进行了背侧椎板切除术，暴露脊髓，并切除了整个纤维性肿块。术后三个月，患者大小便失禁完全消失，仅残留轻度后肢轻瘫，术后六个月仍存在。手术过程使神经症状得到了令人满意的恢复。
