sarcococcygeal dimple

"What's the significance of presacral dimpling in a newborn, and how should it be investigated and followed?"

It's well known that some skin lesions over the spine in a newborn are associated with occult dysraphism -- commonly called spina bifida occulta. In a small proportion of newborns, midline dorsal cutaneous features such as dimples, hair patches, hemangiomas or masses may be clues to underlying pathologies, including dermoid cysts, sinuses, cord syrinx, diastematomyelia and tethered cord. But which of these require further assessment? The commonest skin lesion is the sacral dimple (also called a sacral pit); the vast majority of these aren't linked with any underlying pathology and don't need to be investigated. Several factors, however, should prompt further investigation due to a higher probability of associated pathology, including: dimples lying superior to the intergluteal fold, unusually large (over 5 mm in diameter) dimples, dimples accompanied by other cutaneous lesions, and any abnormal neurologic findings involving the lower extremities, bowel or bladder. If any of these factors are present, consider further investigation with a combination of ultrasound, magnetic resonance imaging (MRI), or neurosurgical consultation.
