Sacral zoster with a primary complaint of difficulty voiding

Motor paresis is a known but rare complication of herpes zoster, estimated to occur between 0% and 6% of all cases.1 The pathogenesis of motor involvement is poorly understood but has been reported occurring with virus reactivation in nerves of the head, trunk, and extremities.1 In addition, visceral motor paresis manifesting as urinary or bowel dysfunction has also been described.1 Here we report a case of a 27-year-old man who presented with a primary complaint of difficulty voiding, which was eventually found to be caused by sacral herpes zoster.
