Sacral Dimple

To diagnose a sacral dimple, your child’s healthcare provider will perform a physical examination. They’ll look at the area near the bottom of your child’s spine. Their healthcare provider will note the size and location of the dimple.

If the sacral dimple looks large, deep or far from the crease of your child’s buttocks, your child’s healthcare provider may order an ultrasound. An ultrasound is a test that can provide images of the spine. Your child’s healthcare provider may also order an ultrasound if they see a skin tag, hairy patch or bruising in the area.
