Hemichorea induced by a sphenoid ridge meningioma.

Background: Movement disorders are rare in brain tumors. We describe a 45-year-old woman with hemichorea, a concomitant contralateral sphenoid ridge meningioma.

Case Description: The meningioma enlarged as her hemichorea worsened, and after meningioma resection, the hemichorea gradually subsided.

Production of an emericellin and its analogues as fungal biological responses for Shimbu-to extract.

This research examined the production of fungal metabolites as a biological response to Kampo medicines. Shimbu-to (SMB) is a Kampo medicine composed of five herbal components: peony root (Shakuyaku), ginger (Shokyo), processed aconite root (Bushi), Poria sclerotium (Bukuryo), and Atractylodes lancea rhizomes (Sojutsu). High-performance liquid chromatography (HPLC) analysis of the fungus Aspergillus nidulans CBS 112.

Effect of ibudilast on the reciprocal inhibitory visual-vestibular interaction closely related to dizziness after cerebral ischemia.

Background: Many patients with chronic cerebrovascular diseases suffer dizziness. Our earlier findings suggested that prolonged terms of dizziness episodes may decrease the regional cerebral blood flow (CBF) in the occipital visual cortex via a remote effect from the vestibular cortex.

Methods: We studied 9 patients who suffered episodes of dizziness since the onset of chronic cerebral ischemia.

Effect of perindopril on vasoreactivity in patients with hypertensive chronic cerebrovascular disease. A comparative analysis of different brain structures.

Background And Purpose: The angiotensin-converting enzyme inhibitor perindopril (CAS 107133-36-8) helps to prevent stroke recurrence by improving cerebral vasomotor reactivity (CVR). Perindopril-induced vasoreactivity changes in different brain structures of patients with chronic cerebrovascular disease were compared.

Methods: The study population consisted of 6 hypertensive patients (mean age 65.

Effect of ibudilast on non-specific symptoms in patients with chronic cerebral ischemia. Analysis of cerebral blood flow.

Background And Purpose: Many patients with chronic cerebrovascular disease complain that dizziness and depression negatively affect their daily lives. In these patients, ibudilast (CAS 50847-11-5) reportedly ameliorated dizziness. The efficacy of ibudilast was investigated and its effect on the cerebral blood flow (CBF) was recorded.

Concurrent hemichorea and migrainous aura--a perfusion study on the basal ganglia using xenon-computed tomography.

A variety of etiologies underlie the neurophysiological imbalance resulting in chorea. We report a 57-year-old woman with a long-history of migraine who suddenly experienced concurrent scintillating scotoma and rapid involuntary movement of her neck and right extremities. Diffusion-weighted magnetic resonance imaging (MRI) failed to detect any fresh ischemic and/or hemorrhagic lesions.

Cerebral thrombosis in a postmenopausal woman on HRT.

We report stroke in a 62-year-old woman who had been on hormone replacement therapy (HRT), estrogen plus progestin, for more than 8 years. She experienced two episodes of transient ischemic attack (TIA), manifesting as right-sided weakness, that persisted for 10-20 min. Magnetic resonance angiography (MRA) obtained before complete stroke, demonstrated severe stenosis of the left middle cerebral artery, without evidence of cerebral infarction.

Diffusion weighted image negative transient ischaemic attack and reversible ischaemic neurological deficit. A report of 10 patients with complete recovery.

Diffusion-weighted magnetic resonance imaging (DWI MRI)-negative transient ischaemic attack (TIA) in hyperacute stroke is a well-known clinical entity. However, no precise analysis of this phenomenon has been reported. We identified 10 patients with TIA or reversible ischaemic neurological deficits (RIND) with no focal hyperintensity on DWI MRI among 108 consecutive acute stroke patients who underwent DWI MRI.

MR imaging findings of spinal posterior column involvement in a case of Miller Fisher syndrome.

The site of lesions causing ataxia in Miller Fisher syndrome (MFS) remains in dispute. A 43-year-old man manifested rapidly progressive left-sided ptosis, bilateral abducens palsy, areflexia, and severe ataxia. Initial MR imaging showed confined lesions of the cauda equina with gadolinium enhancement.
