Acute onset paresthesias and back pain after twisting injury: left sided radiculopathy. There are far left lateral foraminal and perhaps extraforaminal disc protrusions superimposed upon disc bulges and mild facet hypertrophy at L4-5 and L5-S1, which compress the exiting nerve roots at these levels. There is also mild to moderate right neural foraminal stenosis at these levels. In general, the pedicles appear rather short, such that the neural foramina throughout the lumbar spine are not very capacious. Otherwise, there is no significant spinal canal stenosis. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
