Significant hypertrophic facet changes, MRI

User Profile
I need some help understanding my MRI: At L5-S1 level, there are hypertrophic facet changes with cystic-appearing changes noted. There is question of underlying pars interarticular defects. There is moderate disc space height loss. A mild diffusely bulging disc with a small central disc protrusion is evident. There is moderate to severe right and left-sided foraminal stenosis. Incidental note is made of left ovarian follicular cyst. There is a small uterine corpus leiomyoma posteriorly, 8mm in size. IMPRESSION: Degenerative lumbar disc changes at L5-S1. Small central disc protrusion accompanying a diffusely bulging disc. Significant hypertrophic facet changes. Question possible pars defects at this level. CT Imaging may be beneficial in follow up.

(Reactive endplate changes, Modic-type 1 are seen about the endplates at L5 and S1. There is a mild dextroscoliosis.)

It means there are osteoarthritic changes in your L5 S1 along with slight disk herniation. Osteoarthritis changes are like sharp bone fragments that are formed due to constant wear and tear of the bone . Disk herniation is basically coming out of the disc that is present between two vertebral bodies. Also a defect at pars interarticular is questionable. pars interarticular is a joint formed between two vertebras. Thank you
