Prolapse of a lower intervertebral thoracic disc (T10-11) was noticed in a cadaver following examination of serial plastinated sections of the spine. A number of structures were associated with the posteriorly herniated nucleus pulposus, including the posterior longitudinal ligament, fibrous meshworks, venous plexuses and a delicate surrounding capsule. Dimensions of the herniation suggest that the lesion was asymptomatic in life. Thoracic disc prolapse is a rare phenomenon in vivo and is even more infrequently seen in cadavers. This study adds to the minute body of literature on post-mortem thoracic disc herniation and provides insights into detailed pathological changes in the anatomy of surrounding structures following disc prolapse.
