Transverse myelitis (including multiple sclerosis and other causes) Children, young adults Subacute Segmental cord syndrome MRI and CSF
Viral myelitis Any age Acute-subacute Pure motor syndrome or segmental cord syndrome MRI and CSF
Epidural abscess Any age Subacute; may worsen abruptly Segmental cord syndrome MRI
Infarction Usually >60 years Abrupt onset Anterior cord syndrome MRI with diffusion-weighted sequences
Vascular malformation

>40 years (dural fistula)

20s (intramedullary AVM)

Acute and/or stepwise Radiculomyelopathy MRI, spinal angiography
Subacute combined degeneration Any age Slowly progressive Dorsal cord syndrome Vitamin B12 levels

Syringomyelia Children, young adults Slowly progressive Central cord syndrome MRI
Epidural metastasis Usually >50 years Subacute; may worsen abruptly Segmental cord syndrome MRI
Intramedullary tumor Young adults Slowly progressive Central cord syndrome MRI with gadolinium enhancement
