1. We occasionally encounter enhancing spinal cord lesions with difficulty for differentiation between tumorous or non-tumorous myelopathy. There are some imaging clues that can be helpful for differential diagnosis. Tumorous myelopathy usually show more cord expansion, syrinx formation, and more dense patchy enhancement, while non-tumorous myelopathy show as less cord expansion, multisegmental with skipped lesions, and usually vary or disappears on follow up MRI. With these points we may differentiate non-tumorous spinal cord lesions without invasive diagnostic biopsy. 2. In this exhibit, we will present various non-tumorous myelopathy, confirmed by clinical or surgical biopsy and suggest imaging clues, useful for differentiation from tumorous myelopathy

Non–tumorous spinal cord lesions mimicking spinal cord tumor include 1. Multiple sclerosis 2. Neuromyelitis optica (NMO) 3. Subacute cord infarct 4. Toxocara myelitis 5. Subacute combined degeneration 6. Infectious myelitis 7. Vasculitis – SLE, neuro-Behcet`s disease 8. Acute disseminated encephalomyelitis (ADEM) 9. AIDS-related myelopathy 10. Subacute necrotizing myelopathy 11. Radiation myelopathy
