Shunt, back pain, worsening. 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. There is irregularity involving the contour of the thecal sac at the L2-L3 level, the dorsal epidural fat, and in the interspinous soft tissue region which is likely postsurgical. No obvious nerve root clumping to suggest arachnoiditis.Individual levels 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: No significant disc disease. No spinal canal or neural foraminal stenosis.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.
1. No significant disc disease or spinal canal or neural foraminal stenosis at any level.2. Mild distortion of the epidural fat, contour of the thecal sac, and soft tissues at the L2-L3 level is compatible with postsurgical change.
