[Diagnosis of Cochleovestibular Neurovascular Compression Syndrome:A Scoring System Based on Five Clinical Characteristics].

Unlabelled: The optimal method for diagnosing cochleovestibular neurovascular compression syndrome(CNVC)remains controversial, and the aim of this study is to develop a standard diagnostic instrument for the condition. The clinical features of 53 sides of 50 patients with a combination of vertigo, tinnitus, and/or hearing loss were retrospectively evaluated. The following five clinical features were evaluated and given a score of 1 or 0:1)a long history of recurrent vertigo, tinnitus, or hearing loss;2)neurological findings related to positional vertigo, nystagmus, tinnitus, or hearing loss;3)neuro-otological findings involving tinnitus, audiometry, or vestibular testing;4)auditory brainstem response(ABR)evaluation with the detection of a low 25-75% II wave amplitude on the contralateral side and delayed interpeak latency in the I-III or I-V waves(usually low II wave amplitude combined with double peaks and a wide-based form)during ABR evaluation using 80 and 90dB clicks;and 5)the detection of vascular contact with the eighth cranial nerve on magnetic resonance imaging-constructive interference in steady state or air computed tomography imaging.

[Abducens palsy due to unruptured aneurysms of the internal carotid artery in a patient with systemic lupus erythematosus].

We report a rare case of unruptured aneurysms in systemic lupus erythematosus (SLE). A 28-year-old female who had suffered from SLE for 5 years was admitted to our hospital because she noticed diplopia three weeks before. She presented with left abducens palsy on admission.

[Superficial temporal artery-middle cerebral artery anastomosis in a patient of temporal arteritis with internal carotid artery occlusion: a case report].

Temporal arteritis is a rare systemic autoimmune disease and the arteritic process in this case of temporal arteritis involved large and medium-size arteries. Temporal arteritis with internal carotid artery (ICA) occlusion is very rare. We report a case of temporal arteritis with ICA occlusion following superficial temporal artery (STA) -middle cerebral artery (MCA) anastomosis, together with steroid therapy.

Successful neuroendoscopic treatment of intraventricular brain abscess rupture.

Intraventricular rupture of a brain abscess is still associated with a high mortality rate. Here, we report such a case in a patient with normal immunity that was treated successfully using neuroendoscopic approach. A 69-year-old man who had presented with headache and fever developed confusion and restlessness.

Cerebellopontine angle facial schwannoma relapsing towards middle cranial fossa.

Facial nerve schwannomas involving posterior and middle fossas are quite rare. Here, we report an unusual case of cerebellopontine angle facial schwannoma that involved the middle cranial fossa, two years after the first operation. A 53-year-old woman presented with a 3-year history of a progressive left side hearing loss and 6-month history of a left facial spasm and palsy.
