left lower back pain Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is no significant compromise to spinal cana. There is a broad-based left lateral recess disc protrusion present at this level which extends from the midline to the proximal left neural foramen at this level mildly displacing the nerve root at the left lateral recess and mildly encroaching on the left-sided exiting nerve root within the neural foramen but not effacing the fat surrounding the left lateral recess nor the fat surrounding the left-sided exiting nerve root. There are endplate reactive changes with heterogeneous T2 high signal present at this level.At L4-5 there is no significant compromise to spinal canal or neural foramina.At L3-4 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
There is a broad-based left lateral recess disc protrusion at L5-S1 which mildly displaces the nerve root at the left lateral recess and mildly encroaches on the nerve root in the left neural foramen. Associated endplate reactive changes appear to be subacute.
