Adhesive Arachnoiditis after Lumbar Radiculography with Dimer-X and Depo-Medrol

Abstract
Lumber radiculographs were obtained in 252 patients with suspected disk herniation. Fifteen patients who underwent previous radiculography with Dimer-X [meglumine iocarmate] plus Depo-Medrol [6 .alpha. methylprednisdone (21-acetate)] exhibited adhesive arachnoiditis. This was not observed in 6 patients who received Dimer-X alone. No positive correlation between radiological diagnosis of adhesive arachnoiditis and clinical symptoms can be demonstrated. Steroids probably should not be used intrathecally in combination with water-soluble contrast media.
