10 Causes of Pilonidal Cyst
Cause #7: Pilonidal Dimple
A pilonidal dimple, or sacral dimple, refers to the small depression located above the buttocks. Sacral dimples only occur in about 4 percent of the population.
Although most dimples are minor without any underlying disease, it can also be a sign of disease such as spina bifida or kidney issues that can be checked using an ultrasound. Some researchers have also proposed that pilonidal cysts may be due to the pilonidal dimple. More research will be needed to prove this theory.
