Sacral Dimple

Diagnosis

A sacral dimple is typically diagnosed during a newborn’s first physical exam. Most are harmless and require no further evaluation. If the dimple is large or appears with features such as a tuft of hair, a skin tag, a lump or certain skin discolorations, imaging tests may be recommended to look for possible spinal cord issues.

Tests that may be used include:
• Ultrasound, which uses sound waves to create images of structures inside the body.
• Magnetic resonance imaging, or MRI, which creates detailed cross-sectional images using radio waves and a magnetic field. Sedation may be needed to help the child remain still during the scan.

Treatment

A simple sacral dimple does not need treatment. No special care is usually required unless the provider identifies other concerns.

Preparing for your appointment

Most children with a sacral dimple do not need a specific medical visit. If you have questions, you can discuss them at your child’s routine health checkups.

Questions you may want to ask include:
• Does my child need any tests to rule out other causes?
• Does the dimple require special cleaning or care?
• Is any treatment needed?
• Can a sacral dimple be associated with more serious conditions?
