A "secret dimple" typically refers to a sacral dimple, which is an indentation or small pit in the skin located on the lower back, usually just above the crease between the buttocks.
Understanding Sacral Dimples
Sacral dimples are relatively common and are usually harmless. Most are small and shallow, requiring no treatment. They are typically present at birth and are considered a congenital condition.
- Location: Lower back, just above the buttocks crease.
- Appearance: A small, shallow indentation or pit in the skin.
- Significance: In most cases, they are benign and require no medical intervention.
When Sacral Dimples Might Be a Concern
While most sacral dimples are harmless, some can be associated with underlying spinal cord problems. This is more likely if the dimple is:
- Large
- Deep
- Accompanied by other skin abnormalities, such as a tuft of hair, a skin tag, or discoloration
- Located higher on the back
In such cases, further investigation with imaging studies, such as an ultrasound or MRI, might be necessary to rule out conditions like:
- Spina bifida occulta: A mild form of spina bifida where the spinal cord doesn't completely close, but there's no opening on the back.
- Tethered spinal cord: A condition where the spinal cord is abnormally attached to the surrounding tissues, limiting its movement.
Diagnosis and Treatment
- Diagnosis: A doctor can usually diagnose a sacral dimple with a physical examination. If there are concerns about underlying spinal cord problems, imaging tests may be ordered.
- Treatment: Most sacral dimples do not require treatment. If an underlying condition is present, treatment will depend on the specific condition and its severity.
In Summary
A "secret dimple," or sacral dimple, is a common indentation on the lower back. While usually harmless, certain features warrant medical evaluation to rule out underlying spinal cord issues.
