Three cases of chronic spinal epidural abscess following spinal epidural analgesia are presented. Spinal epidural abscess is a relatively rare infectious disease. It has recently increased in frequency due to the increased use of epidural steroid injections and epidural analgesia. It is very difficult to detect the spinal epidural abscess from its variable symptoms. So, it is important in making a diagnosis of epidural abscess to take into account the previous history of epidural analgesia.
