title: Intervertebral disk disease with spinal cord penetration in a Yucatan pig.
abstract: A 9-month-old female Yucatan pig was euthanized after acute onset of paraplegia. Gross and microscopic examination revealed dorsal dissection of the nucleus of the L2-L3 intervertebral disk through the annulus fibrosus, extrusion of nucleus pulposus material through the overlying dura mater and into the spinal cord, and associated acute spinal hemorrhage and necrosis. This is, to the authors' knowledge, the first reported case of intervertebral disk disease in swine.
