Lessons learnt Open spinal cord is referred to as neural placode. Lipoma’s are tightly adhered to the dorsal surface of the cord. Differentiate lipomyelomeningocele from the lipomyelocele. Define the location of lipoma properly. Identify the nerve roots as they exit from the ventral surface of the placode- If not identifed properly may be interuppted at time of surgical intervention.
