Cutaneous stigmata of occult spinal dysraphism.

We describe a 4-year-old Hispanic boy with a dermal pit and an overlying macular vascular malformation in the lumbosacral area. Magnetic resonance imaging of the region revealed an intraspinal lesion at L1-L2. A fibrous tract was excised. A benign lipoma intrinsic to the roots of the cauda equina was noted at surgery. The cutaneous stigmata of occult spinal dysraphisms are reviewed.
