A 42-year-old woman from Ghana initially presented with bilateral optic neuropathy with partial recovery. An MRI scan of the brain performed then showed no demyelinating lesions. Six months later, she developed paraparesis and new urinary incontinence. She was given pulsed methylprednisolone followed by oral prednisolone, but her symptoms continued to worsen.

A repeat MRI scan of the spine is performed, reported as: high-signal lesion from C6–T10.
