Complications
By Mayo Clinic staffRarely, as your child gets older — especially during adolescence and adulthood — the sacral dimple may become infected and form a cyst (pilonidal cyst). This is usually due to hair, oil secretion and friction in the area. If a cyst occurs, your child's doctor may recommend surgery to drain or remove the cyst.
