Findings

Lower lumbar spinal defect with herniation of spinal sac posteriorly. There is accompanying gross dilatation of lateral ventricles with thinning of supratentorial neuroparenchyma.

Careful analysis of spine in transverse and sagittal views are necessary to rule out spinal defects. Often there is accompanying hydrocephalus. Identifying these life compatible defects.. commonly occurring due to folate deficiency, helps prepare the family for post birth interventions as necessary.
