    A 59-year-old woman presented with a spastic gait A 59-year-old woman presented with a spastic gait and weakness in her upper extremities. A T2-weighted sagittal magnetic resonance imaging scan shows cord compression from cervical spondylosis, which caused central spondylotic myelopathy. Note the signal changes in the cord at C4-C5, the ventral osteophytosis, buckling of the ligamentum flavum at C3-C4, and the prominent loss of disk height between C2 and C5.
