Lumbar pain with right-sided radiculopathy Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: There is a disc desiccation with a right paracentral disc protrusion which partially effaces the right lateral recess and contacts the right L5 nerve root. No significant central spinal canal stenosis or neural foraminal stenosis.L5-S1: There is disc desiccation with central and bilateral paracentral disc extrusion with minimal cranial and caudal migration. The extruded disc material measures 8 x 16 x 11 mm in the AP, transverse, and craniocaudal dimensions, respectively, and mildly contacts the bilateral S1 nerve roots, left greater than right. There is mild central spinal canal stenosis at this level. No significant neural foraminal stenosis.Paraspinous soft tissues are within normal limits. There is a simple appearing cystic structure measuring at least 4 cm in diameter in the pelvis which is partially imaged but likely benign in a woman of reproductive age.
1. Disc herniations at the L4-L5 and L5-S1 levels. The L4-L5 disc protrusion contacts the right L5 nerve root and may be source of patient's described right-sided radiculopathy. The L5-S1 disc extrusion slightly contacts the S1 nerve roots, left greater than right.2. 4 cm adnexal cyst is partially imaged and likely benign in this age group.
