Acute Hearing Loss Caused by Decreasing Anterior Inferior Cerebellar Arterial Perfusion in a Patient with Vertebral Artery Stenosis
We report a case of bilateral hearing loss caused by decreased vascular flow in the anterior inferior cerebellar artery (AICA) territory. A 74-year-old man who experienced right hearing loss 5 months ago presented with bilateral deafness and right cerebellar ataxia; however, no ischemic lesion was detected in the bilateral AICA area. After stroke treatment, hearing loss was improved. One month later, we obtained blood flow improvement in the left AICA territory on single –photon-emission computed tomography and vertebral artery stenosis on magnetic resonance angiography.

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Basilar artery occlusion presenting as sudden bilateral deafness: a case report
ConclusionsWhen hearing loss is due to vertebrobasilar occlusive disease, the prognosis is very poor. We suggest that vertebrobasilar stroke be suspected in patients with bilateral sensorineural hearing loss who present with risk factors for stroke such as atrial fibrillation and other neurologic signs.

Teaching NeuroImages: Superficial siderosis due to a dural cervical arteriovenous fistula
A 58-year-old man presented to our hospital with cerebellar ataxia, pyramidal signs, dysarthria, bilateral deafness, and cognitive impairment. These symptoms were consistent with superficial siderosis (SS) of the CNS, confirmed by MRI (figure A).1 Cerebral angiography showed a dural arteriovenous fistula perispinal and pontic with venous drainage in the left foramen C1-C2, fed by meningeal branches of the vertebral artery (figure, B). The fistulous point was clipped. SS of CNS is a rare disease resulting from hemosiderin deposition on the surface of the CNS and cranial nerves.2 At diagnosis, the etiology may...

Case report: Bilateral sudden deafness in acute middle cerebellar peduncle infarction: central or peripheral?
CONCLUSION: Vertebrobasilar diseases due to atherosclerosis should be routinely considered in middle-aged and elderly patients with vascular risk factors and bilateral hearing loss. Bilateral SSNHL can be a prodrome of acute MCP infarction and it can be peripheral. Brain MRI, brain magnetic resonance angiogram (MRA), brain and neck computed tomography angiography (CTA), BAEP, otoacoustic emissions, and Pure Tone Audiogram help to localize and qualify the diagnosis. Bilateral SSNHL localized to the periphery usually improves better and has a good prognosis. Early detection of hearing loss and intervention can help patients ...
