A case of true epidural left hemianalgesia is reported in a man scheduled for elective surgery of the right lower limb. The patient was radiologically diagnosed as having a right unilateral distribution of local anesthetic in the epidural space. The most likely cause is the presence of congenital membranes or posttraumatic adhesions. In such a complication the contralateral paraspinous approach to the epidural space is recommended.
