Female, 34 years old, with new increased nerve root pain. Extensive disc degeneration is evident at the L5-S1 level with loss of disc height and T2 signal as well as fatty degenerative endplate marrow signal. The L5-S1 disc is bulging and there is a superimposed central and left paracentral extrusion which extends superiorly to the mid point of the L5 vertebral body. This extrusion minimally contacts the transiting left S1 nerve root. A mild generalized spinal canal narrowing is evident along with a mild left foraminal narrowing.Mild to moderate facet arthropathy is demonstrated at L4-5 and L5-S1. No other significant degenerative disease is seen. The spinal canal and neural foramina are are otherwise preserved.Spinal alignment is anatomic. Vertebral body morphology is within normal limits. No worrisome marrow replacement is seen.
A disc extrusion is evident at L5-S1 migrating superiorly in the left paracentral zone along the L5 vertebral body. This extrusion mildly contacts the transiting left S1 nerve root and otherwise causes a mild generalized spinal canal narrowing.Facet arthropathy is evident at L4-5 and L5-S1. Otherwise, no significant degenerative disease is seen.
