Closed spinal dysraphism in a 6-month-old mixed breed dog

Area of Science:

• Veterinary Neurology
• Comparative Medicine
• Neurosurgery

Background:

• Spinal dysraphism encompasses neural tube defects resulting in incomplete spinal cord fusion or bone defects.
• This case involves a 6-month-old dog presenting with paraparesis, ataxia, and incontinence, indicative of a spinal cord lesion.

Observation:

• Magnetic resonance imaging revealed a closed spinal dysraphism, specifically a lipomyelomeningocele.
• A fibrous mass was identified, originating from a defect in the L4 vertebra's dorsal lamina, extending towards the skin surface.

Findings:

• Surgical intervention via dorsal laminectomy successfully excised the fibrous mass compressing the spinal cord.
• Postoperatively, the dog showed complete resolution of urinary and fecal incontinence.

Implications:

• Surgical management of canine lipomyelomeningocele can lead to significant neurological recovery.
• This case highlights the importance of advanced imaging and surgical intervention for spinal dysraphism in veterinary patients.
