Diabetic striatal disease: clinical presentation, neuroimaging, and pathology.

Background: Unilateral movement disorders and contralateral neuroimaging abnormalities of the striatum have been sporadically reported as a rare syndrome associated with diabetes mellitus. Despite characteristic imaging findings and clinical manifestations, the mechanism underlying this syndrome is still unclear.

Methods: Six patients with this syndrome were studied clinically and subjected to MRI neuroimaging; one underwent biopsy of the striatum, and another underwent additional MR spectroscopy at 3.

[Progressive multifocal leukoencephalopathy with idiopathic CD4 positive T-lymphocytepenia mimicking a low grade glioma on proton MR spectroscopy. A case report].

A 61-year-old man with no history of HIV infection developed a subacutely progressive dementia and left hemiparesis. Brain MRI showed a high intensity lesion in the right frontal lobe on T2 weighted image. There was no contrast enhancement after gadolinium-DTPA administration.

[Significance of shunt efficacy decision of SPECT on idiopathic normal pressure hydrocephalus].

Purpose: The purpose of this study was to investigate the significance of the shunt-effect evaluation of SPECT in idiopathic normal pressure hydrocephalus (iNPH).

Subjects And Methods: The subjects were 15 patients with possible iNPH, aged 62-83 (mean 75.3, the ratio of males to females to 6:9), who were treated at our department during the period from June to September, 2004.

Stereoselective synthesis of tetrahydronaphthocyclobuta[1,2-d]pyrimidinediones from 5-fluoro-1,3-dimethyluracil and naphthalenes.

Upon UV-irradiation in the presence of piperylene, 5-fluoro-1,3-dimethyluracil (5-FDMU) couples with naphthalenes having either an electron-withdrawing group or an electron-donating group by way of 1,2-cycloaddition via mode selectivity to give the corresponding naphthocyclobutapyrimidines regio- and stereo-selectively.

[Usefulness of carotid duplex ultrasonography in a patient with moyamoya disease].

The patient is a 35-year-old man who had a medical history of epilepsy in childhood. He came to our hospital because of transient disturbance of consciousness and left hemiplegia just after evacuation. At first, we thought that he had epilepsy with Todd's palsy.

Early diagnosis of vertebral dissecting aneurysm: a magnetic resonance angiography study.

We report a patient with dissecting aneurysm who presented with a sudden severe headache without any neurological symptoms. Although brain computed tomography (CT) scan and MRI were negative, magnetic resonance angiography (MRA) showed a pseudocavity in a segment of the left vertebral artery. In addition, the dissecting wall of the left vertebral artery was clearly visualized in the original images of MRA.
