En estos ultimos los anticuerpos se han asociado con la presentacion de enfermedad febril, meningoencefalitis y polyradiculitis
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).
The most common clinical forms of neurobrucellosis that involve the central nervous system (CNS) are meningitis, myelitis, polyradiculitis
and mononeuritis (3).
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).
