Extramedullar etiologies include polyradiculitis
(Guillain-Barre syndrome)  or can be part of the clinical manifestations of ion disorders  like hyperkaliemia or hypercalcemia.
Serious adverse events have been reported, including anaphylaxis, vasculitis, encephalitis, polyradiculitis
, clostridial infections, paresis, and death (3-5).
In the first phase, fever, fatigue, malaise, headache, and arthralgia occur; in the second phase, neurologic signs develop, and the clinical spectrum ranges from mild meningitis to severe encephalitis, myelitis, and polyradiculitis
, sometimes with a fatal outcome (1).
 It occurred year round but was common in the fall (35%), and spring (30%),  which appear as respiratory symptoms but rarely develop CNS manifestation, as studies show low incidence of CNS involvement which is range from 0.1 % to 5% Encephalitis is the most frequent manifestation, but cases of meningitis, myelitis, and polyradiculitis
, as well as many other symptoms (e.g., coma, ataxia, psychosis, and stroke), have been reported.
Here, we report a case with TM and polyradiculitis
related to HZ while he was under immunosuppression after liver transplantation.
Rare neurologic complications secondary to HZ include zoster myelitis, meningoencephalitis, Brown-Sequard syndrome, plexus neuritis, polyradiculitis
, and segmentary zoster paresis (4-7).
It may also present with myelitis or an inflammatory polyradiculitis
of the spinal nerve roots or cranial nerves .
Other complications include secondary bacterial infections, pneumonitis, and polyradiculitis
The neurological presentations have included ataxia and extrapyramidal signs, cranial nerve abnormalities, myelitis, optic neuritis, polyradiculitis
, and seizures (CDC, 2003; Emig & Apple, 2004; Campbell et al., 2002; Gelfand, 2003).
