Although cutaneous herpes zoster eruptions are commonly localized in the lower thoracic dermatomes, motor involvement is rare. The incidence of associated abdominal muscle weakness varies between 0% and 2%, in contrast to herpes zoster localized in the limbs and face.1
A 72-year-old man was admitted to the Unit of Neurophysiopathology, Hospital “Lotti,” Pontedera, Italy, because of a rash, stinging sensation, and abdominal pain on the left side of the abdomen, which had developed 5 weeks earlier. In addition to the rash and pain, the patient reported of swelling restricted to the lower left side of the abdomen.
