Back pain, evaluate for epidural abscess Examination is technically degraded. Vertebral body heights are within normal limits. There is straightening of the lumbar curvature, with otherwise preserved alignment. Diffusely low T1 and T2 signal are noted throughout the bone marrow without focal destructive osseous lesions. The conus medullaris is normal in position. 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.Prominent paraspinous collateral vessels are noted. Ascites.
1. Examination is technically degraded (artifact possible related to extensive ascites) and absence of contrast limits evaluation for small lesions. However, there are no findings to suggest discitis- osteomyelitis, and no epidural or paraspinous collections are apparent to suggest abscess.2. Diffusely low T1 and T2 marrow signal which is nonspecific but can be seen with conditions such as chronic anemia or renal osteodystrophy.
