We reported a 48-year-old man with Behcet disease, who presented with right hemiparesis. His first brain MRI showed multiple enhanced lesions. During the recovery, he had an episode of left 6th nerve palsy without new lesions in a follow-up MRI. Third episode was cervical myelitis, resulting in respiratory difficulty and quadriplegia without any reflexes. The myelitis was not responsive to immunotherapy. He died of respiratory failure complicated with pneumonia. This is a rare case of full-blown neuro-Behcet disease.

A 32-year-old man who had worked at aluminum processing plant for 4 months visited us. He complained of numbness and paresthesia of both foot and hands and weakness of all extremities. Electrophysiologic study showed motorsensory polyneuropathy of diffuse axonal type with focal conduction block. And we discovered higher concentration of n-Hexane in his workplace. On sural nerve biopsy, bubbly enlarged nerve fibers in light microscope and thick myelin sheath and axonal degeneration on electron microscope were found. We diagnosed it as n-Hexane induced neuropathy.

Collet-Sicard Syndrome is one of the variant of the jugular foramen syndromes in which the last four cranial nerves are involved whereas the sympathetic plexus is spared. The possible causes of these multiple lower cranial nerve palsy are variable, including metastasis of systemic malignancy to the base of skull, primary tumor of head and neck, vascular complication, trauma and so on. We experienced two men visited to our clinic with symptoms of headache, hoarsness, swallowing difficulty and showed the evidence of cranial nerve palsy on neurologic examination. Magnetic resonance imaging and computed tomography demonstrated oropharyngeal and hypopharyngeal tumor and electrodiagnostic study supported the diagnosis.

Tuberculous radiculomyelitis (TBRM) is a complication of tuberculous meningitis (TBM), which has been reported rarely in the modern medical literature. We describe a case of TBRM, which developed during the treatment of TBM. A 28-year-old man suddenly developed lower back pain, flaccid paraparesis, urinary incontinence, while the TBM was improving with the treatment at 9th day after admission. Spinal MRI revealed leptomeningeal enhancement along with thoracolumbar spinal canal, thickening of nerve roots, spinal meninges and intramedullary high signal lesion in T2 level.

Intracranial hypotension is a benign disorder characterized by orthostatic headache. It is caused by CSF leakage, therefore its treatment of choice has been epidural blood patch when initial conservative treatments were not effective. We would like to report a 26-year-old patient with recurrent orthostatic intracranial hypotension in spite of the successful epidural blood patch several times. Her headache was caused by myelography 8 month ago. Cisternography showed a CSF leakage at the level of L1 vertebral body. Headache was resolved completely after epidural blood patch and then recurred 3 times several months after blood patch. Now, she is free from headache for 5 months after last blood patch.

Intraoperative Neurophysiological Monitoring (INM) is very useful in monitoring the motorsensory pathway and vascular circulation system during intraspinal, or intracranial neurosurgery. Brainstem Auditory Evoked Potentials (BAEPs) are for detecting the problems along the auditory pathways including, the eighth cranial nerve and brainstem. Motor Evoked Potentials (MEPs) is a useful adjunct to conventional monitoring of Somato-sensory Evoked Potentials (SEPs) during surgery. Visual Evoked Potentials (VEPs) has been regarded as having limited significance for the preservation of visual function during neurosurgical procedures. In this paper, we propose that the most appropriate averaging of the number of inspections in the inspection of each used in the operative field, is good and efficient, functionally.

A 77-year-old man developed acute vertigo and unsteady gait. Neurological examination revealed spontaneous left-beating nystagmus in the primary position. He fell to the left when walking without support. Magnetic resonance imaging showed an acute infarction involving the right parieto-temporal lobe. Although the vertigo and unsteady gait are most often associated with vestibular disorders involving the infratentorial structures, those may occur in cerebral infarction of the parieto-temporal lobe.

Vernet's syndrome is a complex of multiple cranial nerve palsy including ninth, tenth, and eleventh cranial nerves which results from various lesions involving the jugular foramen. There are several kinds of lesions that can cause Vernet's syndrome. It includes congenital cholesteatoma, vascular lesions such as protruded jugular bulb, infections such as external otitis or abscess, and tumoral lesions such as schwannoma or paraganglioma. We present a rare case of Vernet's syndrome caused by non-specific inflammatory mass lesion in the neck area sparing jugular foramen.

In clinical neurology various different electrophysiological tests are widely used to demonstrate the unsuspected malfunctioning in the nervous system and to monitor over time the clinical status of patients. In addition clinical neurologists and neurosurgeons take advantage of the intraoperative monitorings to increase the quality of neurosurgical operations in the posterior fossa, in the spinal cord, or in visual pathways. In the field of movement disorders, elecrophysiolgical tests provide neurologists with making accurate differential diagnoses with useful therapeutic stratergies as well as with investigating the pathophysiological machanisms. By using the electromyographic tests it could be possible for us to evaluate the types of blephalospasm, the extent of hemifacial spasm, the level of myoclonus, and the prime muscles of torticollis etc. Sometimes the myographic guidance may be critical for choosing the exact injecting site of botulinum toxin. These several decades various electroencephalographic and evoked potential tests has been utilized in the electrophysiological laboratories to understand the basic pathophysiology of myoclonus, spasticity and other central motor dysfunctions. It could be one of the breakthroughs in the area of behavorial neurology that the brain function can be mapped by the spontaneous or evoked electrical activities of nervous system since the movement related potentials (MRPs) had been studies for several decades. Various reflex tests such as masseter reflex, blink reflex, click evoked vestibulocollic reflex, facial reflex, stretch reflex, flexor reflex, H-reflex, H-reflex recovery curve, vestibular inhibition of H-reflex, reciprocal inhibition, recurrent or Renshaw reflex, Ib inhibition, cutaneous reflex have been also used to understand normal or abnormal physiology in movement disorders. Polysomnography, posturography and gait studies are also applied in clinical neurology in association with with movement disorders which are useful in deciding the treatment regimen.
