Middle cerebral artery dissection (MCAD) is a rare cause for ischemic stroke and is often associated with headache and hemispheric symptoms. In the present report, limb shaking is found to be a major symptom of spontaneous MCAD in a young male. The diagnosis of MCAD is based on the intramural hematoma directly visualized in MR T2-weighted images and supported by serial evolution of transcranial...

BACKGROUND AND PURPOSE Transcranial color-coded real-time sonography has been developed as a promising new bedside procedure to monitor central nervous system parenchymal and vascular pathology; the present study was designed to investigate the potential role of galactose microparticles (SH U 508 A) as a new ultrasound contrast-enhancing agent for transcranial sonography. METHODS Ten patients...

Fahr disease, also known as bilateral striopallidodentate calcinosis, is a rare degenerative neurologic disorder characterized by almost symmetric calcifications of the basal ganglia, the cerebellum dentate nuclei, the thalami, and the white matter of the cerebral hemispheres. Bilateral striopallidodentate calcinosis manifests as familial autosomal dominant but also as sporadic forms. Movement ...

BACKGROUND AND PURPOSE MR imaging-guided focused sonography surgery is a new stereotactic technique that uses high-intensity focused sonography to heat and ablate tissue. The goal of this study was to describe MR imaging findings pre- and post-ventralis intermedius nucleus lesioning by MR imaging-guided focused sonography as a treatment for essential tremor and to determine whether there was an...

BACKGROUND AND PURPOSE Atherothrombotic disease of the middle cerebral artery (MCA) frequently occurs in Asian populations. This abnormality can be noninvasively assessed with transcranial Doppler sonography (TCD) and computed tomographic angiography (CTA). To our knowledge, the usefulness of TCD sonography compared with CTA in the diagnosis of nonembolic MCA disease has not been studied. MET...
