Post-chemonucleolysis computed tomographic findings.

The CT findings observed 6 months and 2 years after chemonucleolysis in 50 and 34 patients are reported. Emphasis is placed on the persistence of the hernia image in nearly 70% of the cases, together with an increase in degenerative intradiscal signs and degeneration of the facet joints; however, this did not lead to poor results 2 years after chemonucleolysis.
