I had an emergency lumbar microdiscectomy on L5/S1 a little over 3 months ago following a loss of bladder control (which is now resolved) and a severe herniation. I just had a follow up MRI due to some residual back pain and intermittent, mild leg pain. My doctor is out of office now due to the holiday and am having a little trouble understanding my MRI results; I am not sure if it means the L5/S1 disc has reherniated, or is just bulging, and if the disc bulge/material is what is indenting the left S1 nerve root. Any help would be greatly appreciated! Thanks!
L5-S1: Previous left hemilaminectomy. Generalized disc bulge with broad-based central disc protrusion causing mild canal stenosis. There is mild indentation of the left S1 root. No enhancing scar tissue noted.
IMPRESSION: Previous left hemilaminectomy at L5-S1 level. Generalized disc bulge with broad-based central disc protrusion at L5-S1 level causing mild canal stenosis. There is indentation of left S1 root in the lateral recess. No significant enhancing scar tissue noted.
