CT Scan of Temporal Bones Without Contrast: Negative Findings

Radiology Report  
  
Patient Name: John Doe  
Patient ID: 123456  
Date of Examination: October 15, 2023  
Referring Physician: Dr. Jane Smith  
Examination: MRI of the Lumbar Spine  
  
Clinical History:  
The patient presents with chronic lower back pain radiating to the left leg, with intermittent numbness and tingling. Symptoms have persisted for the past three months, with no significant relief from physical therapy or medication.  
  
Technique:  
MRI of the lumbar spine was performed using standard protocol sequences, including T1-weighted, T2-weighted, and STIR images in sagittal and axial planes.  
  
Findings:  
- Alignment: Normal lumbar lordosis is maintained. No evidence of spondylolisthesis.  
- Vertebrae: Vertebral body heights are preserved. Mild degenerative changes noted with endplate sclerosis at L4-L5 and L5-S1.  
- Intervertebral Discs:  
  - L1-L2, L2-L3, L3-L4: No significant disc bulge or herniation.  
  - L4-L5: Mild disc bulge with slight effacement of the thecal sac. No significant neural foraminal narrowing.  
  - L5-S1: Moderate disc herniation with impingement on the left S1 nerve root.  
- Spinal Canal and Neural Foramina: No significant spinal canal stenosis. Mild narrowing of the left neural foramen at L5-S1.  
- Soft Tissues: Paraspinal soft tissues appear unremarkable.  
  
Impression:  
1. Moderate disc herniation at L5-S1 with impingement on the left S1 nerve root, correlating with the patient's symptoms of left leg radiculopathy.  
2. Mild degenerative changes at L4-L5 and L5-S1.  
  
Recommendations:  
Consider referral to a spine specialist for further evaluation and management, including potential interventional procedures or surgical consultation if symptoms persist.
