Large disc herniation at C5–C6. At autopsy
the cervical spine was intact, all specimen radiograms were normal.
The nucleus pulposus is extruded through a rupture of the annulus,
compressing the spinal cord against the lamina. Note ischemia and
anterior spinal artery obliteration. Above and below the herniation,
the epidural sinusoids are widened, forming large triangular venous
compartments. The ligamentum flavum is avulsed from the C5–lamina.
Multiple uncovertebral– and facet joint injuries and posterior
annulus and ligamentum flavum ruptures were also found.
