Cervical Myelopathy Due to Direct Cord Compression by Posterior Inferior Cerebellar Artery Associated with Aberrant Vertebral Artery.

Background: The effectiveness of surgical microvascular decompression (MVD) of the vertebral artery (VA) for treating conditions such as trigeminal neuralgia or hemifacial spasm is well known. However, the use of MVD for a case in which the posterior inferior cerebellar artery (PICA) is directly compressing the high cervical cord has not been reported.

Case Description: A 48-year-old male was diagnosed with a rare case of myelopathy due to the PICA directly compressing the high cervical cord.

Arteriovenous malformation of the vestibulocochlear nerve.

We describe a rare case of an arteriovenous malformation (AVM) embedded in the vestibulocochlear nerve presenting with subarachnoid hemorrhage (SAH) treated by microsurgical elimination of the main feeding artery and partial nidus volume reduction with no permanent deficits. This 70-year-old woman was incidentally diagnosed 4 years previously with two small unruptured tandem aneurysms (ANs) on the right anterior inferior cerebral artery feeding a small right cerebellopontine angle AVM. The patient was followed conservatively until she developed sudden headache, nausea and vomiting and presented to our outpatient clinic after several days.

Endoscopic third ventriculostomy for hydrocephalus due to unruptured pineal AVM: case report and review of the literature.

Introduction: Arteriovenous malformations (AVM) are considered to be static congenital lesions; however, a subset may possess dynamic pathophysiological capabilities of growth, regression or other morphological changes with time. We report on an adult patient harboring a pineal AVM who presented with progressive symptoms of obstructive hydrocephalus and was successfully treated by endoscopic third ventriculostomy (ETV).

Clinical Presentation: This 63-year-old man was incidentally diagnosed 8 years previously with an asymptomatic unruptured pineal AVM and followed conservatively until he developed a progressive impairment in consciousness with gait apraxia and incontinence over a period of 2 months.

Giant internal carotid artery aneurysm manifesting as difficulty in swallowing: case report.

A 66-year-old man presented with a rare case of a giant aneurysm of the internal carotid artery manifesting as difficulty in swallowing, resulting in severe malnutrition. Initial examination found a pulsating mass protruding from the posterior wall of the pharynx in the oral cavity. The patient had left hemiplegia caused by cerebral infarction one year previously.

[Effectiveness of kampo medicine gorei-san-ryo for chronic subdural hematoma in very elderly patients].

Chronic subdural hematoma (CSDH) is mainly a disease of the elderly. Widespread use of CT and MRI has resulted in the discovery of CSDH cases with no or minimum symptoms in the elderly. Treatment is by surgical evacuation, although small hematoma may resolve spontaneously.

Adrenomedullin enhances therapeutic potency of mesenchymal stem cells after experimental stroke in rats.

Background And Purpose: Adrenomedullin (AM) induces angiogenesis and inhibits cell apoptosis through the phosphatidylinositol 3-kinase/Akt pathway. Transplantation of mesenchymal stem cells (MSCs) has been shown to improve neurological deficits after stroke in rats. We investigated whether AM enhances the therapeutic potency of MSC transplantation.
