Background  Spinal cord infarction (SCI) after epidural anesthesia is quite rare. Although most cases of perioperative SCI are associated with aortic, cardiac, or spinal surgery, and/or abnormal preoperative conditions, such as spinal stenosis or hypercoagulopathy, intraoperative events, such as severe hypotension or epidural puncture and catheterization, can be contributory factors.    Case presentation  A 52-year-old male was underwent laparoscopic gastrectomy. Before induction of general anesthesia, an epidural catheter was placed without any problems. The patient had no pain and no complaint just after the operation, but suddenly complained of back pain and anuria, and could not move either of his lower limbs 30 h after the operation. As we thought that the incident would be caused by the migration of the epidural catheter into the subarachnoid space, we removed the catheter, but there was no recovery of the symptoms even 20 h later. The magnetic resonance imaging (MRI) scan showed no hematoma in the epidural space but an abnormal signal within the spinal cord, extending from the Th3 to Th8 levels, which was consistent with the SCI. Unfortunately, the patient’s recovery from the paraplegia and abnormal sensation was poor.    Conclusions  When a patient complains of lower limb muscle weakness and/or abnormal sensations, it is important to perform an MRI examination and treatment as early as possible to avoid permanent paraplegia, especially after epidural puncture and catheterization.
