To determine the pathological structure of herniated intervertebral disc which was enhanced on MRI by using Gd-DTPA, the relation between preoperative Gd-DTPA enhanced MR and histological findings of seven herniated lumbar intervertebral discs (six sequestrated and one extruded) were examined. All of herniated disc materials were enhanced marginally on early postcontrast T1-weighted images. The enhanced area of the disc materials herniated long duration was larger than that herniated short duration. Histologically, there were fibrous granulation tissues with abundant blood vessels around the all of disc materials. The longer the period from the onset to the operation was, the larger the granulation tissue on histologically as well as the enhanced area on Gd-DTPA enhanced MRI findings existed. In conclusion, the tissue enhanced by using Gd-DTPA was granulation around the disc materials.
