Segmental paresis affects 3% to 5% of patients with cutaneous herpes zoster. This retrospective case report describes three patients with cutaneous zoster followed within several days by segmental weakness involving limb muscles. The authors also reviewed the literature and found 135 additional cases to illustrate the clinical characteristics of this syndrome.
The three cases involved the proximal arm (two cases) and the proximal leg (one case). All three patients received oral antiviral therapy, and two were subsequently treated with intravenous acyclovir and methylprednisolone, followed by oral prednisolone. All patients had good functional recovery, even though one refused steroids and intravenous antivirals.
