• A patient with non-Hodgkin's lymphoma who was previously treated with chemotherapy and radiotherapy was seen with intestinal pseudoobstruction due to paralytic ileus associated with herpes zoster (varicella zoster) infection. The infection was accompanied by a polydermatomal rash with typical morphologic characteristics, followed by cutaneous dissemination and the syndrome of inappropriate antidiuretic hormone (SIADH), as well as myotomal paresis. The diagnosis was supported by cytology and by culture of the virus from the CSF. The isolation of the virus from the CSF, coupled with abnormalities of the patient's mental status and CSF, indicate that meningoencephalitis occurred and probably accounted for the SIADH. The patient had a spontaneous and complete recovery. To our knowledge, this is the first report of SIADH associated with herpes zoster infection.
