title: Herpes zoster in the T1 dermatome presenting with Horner's syndrome, radicular weakness, and postherpetic neuralgia.
abstract: Herpes zoster is caused by varicella zoster virus infection involving the dorsal root ganglia of spinal nerve roots. This common problem can be associated with multiple neurological abnormalities. We present a case of Herpes zoster affecting the T1 dermatome associated with ipsilateral Horner's syndrome and radicular weakness.
