CAN ANYONE TELL ME WHAT THIS MEANS?? MRI OF THE LUMBAR SPINE WITHOUT AND WITH GADOLINIUM: At L4-5 there has been left semi-hemilaminotomy and microdiscectomy in the interval. The component of the disc herniation within the left paracentral and lateral recess aspect has been removed. However, there is nonenhancing low T2 signal still present within the central and right paracentral aspect, which measures about 11 x 7 x 11 mm (transverse x AP x CC dimensions), representing residual vs. recurrent disc herniation. Enhancing component of epidural fibrosis noted in the left lateral recess and circumferentially along the disc material extending from the superior to mid aspect of L4 to the superior aspect of the L5 vertebral body within the epidural aspect. Enhancing scar/granulation tissue within the left paraspinous soft tissues with susceptibility artifact in the left paraspinous soft tissues. There is also susceptibility artifact at the left facet. Moderate central canal stenosis with slightly improved patency of the left lateral recess and left paracentral aspect from previously. Benign reactive mixed Modic type 1 to 2 changes and benign reactive endplate enhancement, likely postsurgical, at the posterior aspect on the left.Linear susceptibility artifact extending from the left paraspinous soft tissues to the level of deep to the posterior longitudinal ligament abutting the L4 vertebral body (as on image 8 of series 15), which is likely postsurgical, related to the linear tract of the surgery. At L5-S1 the posterior central annular fissure is slightly more conspicuous with small broad-based predominantly central disc protrusion minimally caudally prolapsing and causing mild effacement of the ventral thecal sac.Mild-to moderate facetal hypertrophy and left mild foraminal stenosis.. The overall alignment is anatomic. Disc space narrowing, which is mild, at L5-S1 and L4-5 with disc desiccation from L3-4 to L5-S1 again noted and benign reactive endplate Modic type 2 changes at L5-S1. The distal spinal cord and conus medullaris are of normal signal intensity. The conus is at the level of T12-L1. IMPRESSION: Left semi-hemilaminotomy with microdiscectomy with interval removal of the disc material that was previously noted in the left lateral recess aspect. However, a moderate llow T2 signal which is nonenhancing, representing residual or recurrent disc herniation is still present within the central to right lateral recess aspect causing moderate central canal stenosis. Epidural fibrosis, which is enhancing, at the site of discectomy at the left lateral recess. Susceptibility artifact, which is likely postsurgical, projecting at the left posterior elements and extending to the level of the L4 vertebral body.
