Thank you for the queryPilonidal sinus
is seen on the natal cleft of the buttocks that often contains hair and skin debris, when infected secondary to skin infection
, or prolonged sitting or due to tuft of hair grown it get secondary infected and cyst is formed .
Treatment is antibiotics and avoid prolonged sitting . Since your MRI spine is normal there is no chance of spinal cord
anomaly in your case.
Once infection ascends to arachnoid
space forming fistulla and inner connection establishes then only spinal cord will be affected otherwise chances are very less as spinal cord ends at L2 vertebra and pilonidal region is located at the tail bone (coccygeal location)
