A paraspinal abscess following spinal anaesthesia for caesarean section and patient-controlled epidural analgesia for postoperative pain

We present a rare case in which a healthy parturient developed a paraspinal abscess after spinal anaesthesia for caesarean section and epidural analgesia for postoperative pain management. The catheter was in situ for 58 h. Backache was the initial and major symptom. A concealed course with no neurological deficit resulted in a delayed diagnosis and treatment in this case. The infection was not diagnosed until 20 days after the removal of the epidural catheter when there was a purulent discharge from the epidural puncture site. Surgical drainage was required. Anaesthesiologists should be aware that serious epidural analgesia-related infections can happen in extra spinal-epidural spaces. Vigilance for these infections, especially in postpartum patients with backache, is needed.
