Overview
A sacral dimple is an indentation or pit in the skin on the lower back that is present at birth in some babies. It is usually located just above the crease between the buttocks. Most sacral dimples are harmless and don't need treatment. However, in some cases, a sacral dimple may be a sign of a serious underlying spinal problem, such as spina bifida occulta or tethered cord syndrome. If a healthcare provider finds a large sacral dimple or one that is near a tuft of hair, skin tag, lump, or discolored area, they may recommend an imaging test to further evaluate the issue.
Understanding the disease
Symptoms
The symptoms of a sacral dimple include:
- An indentation or pit in the skin on the lower back, usually located just above the crease between the buttocks.
- In some cases, a sacral dimple may be associated with a nearby tuft of hair, skin tag, lump, or discolored area, which can increase the risk of spinal complications.
- In newborns, a sacral dimple may be a sign of a serious underlying spinal problem, such as spina bifida occulta or tethered cord syndrome. It's important to note that most sacral dimples are harmless and don't require treatment. However, if the dimple is large or appears near a tuft of hair, skin tag, lump, or discolored area, a healthcare provider may recommend an imaging test to check for any underlying spinal problems.
Assessment and Diagnosis
Diagnosis
A sacral dimple is diagnosed through a physical exam, typically during a baby's first exam. If the dimple is large or appears with a nearby tuft of hair, skin tag, or lump, or specific types of skin discoloration, the healthcare provider may recommend imaging tests such as an ultrasound or magnetic resonance imaging (MRI) to check for spinal cord problems. No special preparation is needed for the appointment, and questions can be asked to clarify the need for tests or treatment.
Management and Treatment
Treatment
There are no specific treatments for a sacral dimple itself, as it is typically a harmless congenital condition. However, if a sacral dimple is associated with a serious underlying abnormality of the spine or spinal cord, treatment would depend on the underlying cause. In some cases, healthcare providers might recommend imaging tests to evaluate the spine and spinal cord, and if a spinal problem is identified, treatment would be based on the underlying cause. Treatment options may include monitoring, medications, physical therapy, or surgery. It's important to discuss any concerns about a sacral dimple with a healthcare provider, who can provide guidance and recommendations based on the individual case.
