title: Subdural or epidural? Confirmation with magnetic resonance imaging.
abstract: An epidural performed for obstetric analgesia was initially characteristic of a subdural block but subsequently behaved as a normal epidural. Radiological confirmation of the catheter having been subdural was established by performing a magnetic resonance imaging scan.
