title: [Sacral dimple: What form of management is best?].
abstract: A sacral dimple measuring less than 5mm, within 25mm of the anus on the median line, with no other cutaneous anomaly, does not require any complementary examination. Parents can be reassured. However, any cutaneous depression in the sacrolumbar region not respecting these criteria must be considered as an occult dysraphism until proved otherwise. A medullary ultrasound examination and a consultation with a specialist (pediatric neurosurgeon) are necessary. The dermic sinus is the main differential diagnosis, with favorable outcome in case of early treatment before any infectious complication arises. Conversely, the risk of permanent sequelae is high if neglected or in case of late diagnosis.
