Hemidystonia secondary to pediatric thalamic glioblastoma: a case report.

Introduction: Thalamic tumors are rare and uncommonly manifest as movement disorders, including hemidystonia. Despite this association, little is known about the evolution of hemidystonia.

Case Description: We report on a 11-year-old boy who complained of hypaesthesia and fine motor problems in the left hand.

Extended long-term (> 5 years) outcome of cerebrospinal fluid shunting in idiopathic normal pressure hydrocephalus.

Background: Shunt surgery has been established as the only durable and effective treatment for idiopathic normal pressure hydrocephalus.

Objective: We evaluated the "extended" long-term follow-up (> 5 years) in a prospective study cohort who underwent shunting between 1990 and 1995. A secondary objective was to determine the cause of death in these patients.

Calcifying pseudoneoplasm of the inferior colliculus: an unusual location for a rare tumor: case report.

Objective: Quadrigeminal plate lesions are rare and usually present with a silent clinical course. Tumors, vascular lesions, inflammatory and infectious processes have been described in this region. Calcifying pseudoneoplasms, also reported as fibro-osseous lesions, cerebral calculi, and brain stones, are unusual lesions in the central nervous system.

Ultrasonic aspiration in neuroendoscopy: first results with a new tool.

Neuroendoscopic techniques are often considered inapplicable to lesion resection because most lesions are too large for effective endoscopic resection in an appropriate time frame. To evaluate the potential of ultrasonic aspiration in neuroendoscopic procedures, the authors developed a new handpiece for endoscopic application. The instrument was subsequently tested in 10 cadaveric pig brains and applied in 5 clinical cases.

Waterjet dissection of the vestibulocochlear nerve: an experimental study.

Object: Waterjet dissection has been shown to protect intracerebral vessels, but no experience exists in applying this modality to the cranial nerves. To evaluate its potential, the authors examined waterjet dissection of the vestibulocochlear nerve in rats.

Methods: Lateral suboccipital craniectomy and microsurgical preparation of the vestibulocochlear nerve were performed in 42 rats.
