A patient is reported with a painless, progressive cauda equina lesion due to arachnoiditis, the result of the contrast medium 'Thorotrast' (thorium dioxide) introduced into the brain over 30 years previously. Contrast medium introduced into the lumbar spine can give rise to aseptic adhesive inflammation (arachnoiditis). It rarely gives rise to clinical problems but, when it does so, is usually associated with back pain and only very rarely with progressive neurological deficit.
据报道，一名患者因蛛网膜炎出现无痛性、进行性马尾病变，这是30多年前注入脑内的造影剂“钍造影剂”（二氧化钍）所致。注入腰椎的造影剂可引发无菌性粘连性炎症（蛛网膜炎）。它很少引发临床问题，但一旦引发，通常与背痛相关，极少与进行性神经功能缺损相关。
