 Abstract
- Ramsay-Hunt syndrome is an infectious disease caused by the varicella zoster virus. It is usually associated with facial and vestibulocochlear nerve palsy, but other cranial nerve dysfunction can be accompanied. We present a 68 years-old woman with abducens nerve palsy associated with Ramsay-Hunt syndrome. She showed abduction limitation of left eye with peripheral facial palsy and vestibulopathy of the left side. Varicella zoster virus polymerase chain reaction of cerebrospinal fluid were positive and internal auditory canal magnetic resonance imaging was revealed enhancement of labyrinthine segment of left facial nerve. Although abducens nerve palsy is uncommon feature of Ramsay-Hunt syndrome, but it can be developed by several different mechanisms.

Abstract
- A 84 year-old woman presented with a two weeks history of dizziness, slurred speech and ataxia. The neurologic exam showed spontaneous left beating nystagmus, horizontal gaze evoked nystagmus and limb ataxia. A few weeks earlier, she had an upper airway infection. Brain MRI revealed diffuse leptomeningeal enhancement in the both cerebellar hemisphere and brain SPECT showed hyperperfusion in both cerebellar hemisphere. Extensive laboratory studies with cerebrospinal fluid analysis did not reveal any etiologic factors. She was started on methylprednisolone(1g/day for 7days), gradually improved over the weeks. Post infectious cerebellar ataxia is a neurologic complication that occasionally follows systemic viral and bacterial infections. This case demonstrates that cerebellar abnormalities can be detected by brain MRI and SPECT.

Abstract
- According to the Barany Society classification of vestibular symptoms, positional dizziness or vertigo is defined as dizziness or vertigo triggered by and occurring after a change of head position in space relative to gravity. Thus, positional dizziness or vertigo should be differentiated from orthostatic dizziness or vertigo, which is triggered by and occurs upon rising. Benign paroxysmal positional vertigo(BPPV) is the most common positional vertigo and accompanied by a characteristic paroxysmal positional nystagmus. But a problem occasionally encountered in clinical practice is the presence of a positive history of BPPV with a negative diagnostic maneuver for positional nystagmus. Orthostatic hypotension (OH) may be dependent upon various neurogenic and non-neurogenic disorders and conditions. Combination of non-pharmacological and pharmacological treatment improve orthostatic tolerance.
