Dear, I have a Pilonidal Cyst right now and a take antibiotics. My doctor says I must have u Pilonidal Sinuse surgery. And the surgent said that under my Cyst there are few small holes formes as sinuses - and at the moment they are unactive. I noticed these holese fiftheen years ago. Six years ago I started to have u numblness in lower part of the body - I was hospitalized for two weeks (had brain MR test, all blood tests, muscle examination, lumbal punction etc.. and all the results were negative) so they never find out what happened. I am reading about connection betwwen the Pilonidal Sinuse and spinal cord - is it possible that spinal  cord affection (or something alike) caused by Pilonidal Sinuse caused these symptoms? Im sorry for my not so well English, Im writing You from Croatia and Im desperate.. Thank You very Much.Kind regards.
Hi, 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 fistula and inner connection establishes then only spinal cord will be affected otherwise chances are very less than spinal cord ends at L2 vertebra and colonial region is located at the tail bone (coccyges location)Regards Chat Doctor.
