Horner's Syndrome with Unilateral Brachial Plexus Blockade Mimicking Cerebrovascular Accident Following Lumbar Combined Spinal Epidural Analgesia for Labor.

Horner's Syndrome (HS) with brachial plexus involvement following lumbar epidural anesthesia may be a startling event for the patient and providers. We present a case of Horner's Syndrome and complete brachial plexus blockade following epidural bolus of lidocaine for labor analgesia that was initially misdiagnosed as a cerebrovascular accident. Use of the catheter was discontinued and the episode resolved with expectant management. This complication is otherwise benign and resolves without sequelae.
