✓ Eighteen cases are presented in which magnetic resonance (MR) imaging demonstrated two types of lesions patients with cervical spondylotic myelopathy. In the first type, localized spinal cord changes at level compression, consistent myelomalacia, were revealed best T 2 -weighted images as high-intensity signals. second either cystic necrosis or secondary syrinx noted locally, and/or extending longitudinally up, down inside cord. These latter low-intensity signals on 1 MR and a signal-void sign (moving fluid) proton-density images. It is suggested that segmental bar represent early proton from pressure around same zones evolve into gray-matter enhancement regions shown “snake-eyes” delayed computerized tomography (CT) after myelography. The longitudinal thought to be pencil-shaped evolving late stages (and usually found anterior portion dorsal columns during CT myelography). As continues improve, these will more clearly within substance.
