Abstract
An 83-year-old man, suffering from lumbago and leg pain due to lumbar disc hernia and spinal canal stenosis, had received epidural block with steroid treatment once a month. After the ninth epidural block, he complained of increased leg pain and right iliopsoas and epidural abscesses were revealed by magnetic resonance imaging. Puncture of the iliopsoas abscess under computed tomographic guidance was conducted and antibiotics were also administered about for 30 days thereafter. After the therapy, his leg pain was alleviated remarkably as the abscesses of the iliopsoas muscle and epidural space had almost vanished. Inflammatory changes, however, were prolonged. He was discharged without any neurological sequelae after 33 days of hospitalization.
