What tests will be done to diagnose Brown-Séquard syndrome?

If your healthcare provider suspects you may have Brown-Séquard syndrome (BSS), they’ll likely order the following tests:

• Magnetic resonance imaging (MRI): This is a painless test that produces very clear images of the organs and structures within your body using a large magnet, radio waves and a computer. MRI is the most useful imaging test for BSS because it can help identify structural damage in your spine and can be useful in evaluating non-traumatic causes of BSS.
• Myelogram and computed tomography (CT) of your spine: If you’re unable to undergo an MRI scan, your provider will likely order a myelogram immediately followed by a CT scan of your spine. These tests can reveal nerve tissue damage on one side of your spinal cord. A myelogram is an imaging procedure that examines the relationship between the vertebrae and disks in your spinal column through your spinal cord, nerves and nerve roots. A CT scan uses X-rays and computers to produce detailed images of structures inside your body.
• Blood tests: If the cause of the BSS is unclear, your provider may order certain blood tests to check for an infection that might be causing the condition.
• Lumbar puncture (spinal tap): If your provider suspects that BSS is caused by multiple sclerosis, transverse myelitis or tuberculosis, they may perform a lumbar puncture to get a sample of cerebrospinal fluid (CSF) for analysis. CSF is the clear liquid that surrounds your spine and brain.
