OBJECTIVE
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
BACKGROUND
The development of an intraparenchymal cyst following deep brain stimulation (DBS) surgery is an uncommon complication that lacks a clearly defined management strategy. The pathophysiology is not known and may be related to perielectrode edema or cerebrospinal fluid tracking. Previous
Serial postoperative magnetic resonance (MR) studies were obtained in 21 patients who underwent somatotopically placed stereotactic radiofrequency (rf) ventralis lateralis thalamotomy for the control of movement disorders. The MR studies were reviewed to determine the MR characteristics of
To assess the intraoperative neuroimaging findings in patients treated with transcranial MR-guided focused ultrasound (tcMRgFUS) thalamotomy using 1.5T equipment in comparison with the 48-h follow-up.Fifty prospectively enrolled patients undergoing To evaluate effect of the calcium-channel blocker nicardipine in essential tremor (ET), 14 patients with ET affecting upper limbs underwent a cross-over study with nicardipine (1 mg/Kg/day) and propranolol (160 mg/day). Evaluation (baseline and 1 month after each drug) was done by using the
Focused ultrasound thalamotomy is an emerging treatment for essential tremor, and it is ideal for studying reorganization in the human brain after acute injury because it creates a controlled thalamic ablation without breaching the cortex. However, there is not yet a metric capable of This paper describes a topiramate induced acute bilateral angle-closure glaucoma. This rare adverse effect is an idiosyncratic reaction characterized by uveal effusion and lens forward displacement, leading to increased intraocular pressure and vision loss. We describe a 55 year-old white woman with
A chart review from 151 dysphonic patients over the age of 60 was done to define aging related voice disorders. Overwhelmingly, patients suffered from dysphonia due to disease processes associated with aging rather than to physiologic aging alone. These include: 1. central neurological disorders
OBJECTIVE Magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy was recently approved for use in the treatment of medication-refractory essential tremor (ET). Previous work has described lesion appearance and volume on MRI up to 6 months after treatment. Here, the authors report on the
