Hello! 18 years ago I fell in the street and him my right cheek (bottom) on the point of a cement block. After the enormous pain, swelling and bruising passed I had x-rays and an MRI. The doctor said I broke the muscle in my butt. The dent has never gone away. Every day I have this discomfort and from time to time I m told the muscle gets inflammed and I m given oral steroids - have had epidural blocks which work but do not last. I recently had a pelvic MRI requested by my spine doctor. What is he looking for? Thank you so much! Madalene I just saw that I have to pay $15 to receive an answer. I am sorry, being unemployed at this time I cannot afford to pay the fee. Thank you anyway for reviewing my question.

Hinever mind the money part. This forum is always there to help and guide. I believe Pelvic MRI may be to assess the parts of pelvic bone like symphysis pubis and its joint, the sacroiliac joints, the tail bone or coccyx, the social tuberosities from where many hip muscles take origin and ilium bones from where buttock muscles originate.apart from this soft organs like binary bladder, uterus, rectum are seen on pelvic Many inflammation in the joints mentioned, or at sites of muscles origin of buttocks, rents in muscles, ligaments,tendons shall be visible. Your primary problem seems to be the seat of buttock, (we sit on schism, a seat Goethe workup may be for a comprehensive view18 years is a long time and rent in muscle may have healed with fibrosis, fat deposits. Myositis or inflammation may be another possible cause or some bony changes in schism, its tuberosity may be recurring cause of painterly to have elaborated medical terms, but that's how things can be explained Chat Doctor.
