Intraspinal extradural teratoma mimicking neural sheath tumor in infant.

Introduction: An intraspinal teratoma that is located entirely extradurally is unusual both in children and in adults.

Case History: The authors present a case of an 8-month-old male infant with an extradurally arising intraspinal mature teratoma located from T-2 to T-4, who had suffered from progressive paraparesis (grade 1). The patient did not have any stigmata or anomalies suggesting spinal dysraphism.

Posteroventral pallidotomy in medically intractable postapoplectic monochorea: case report.

Background: Posteroventral pallidotomy is a widely accepted surgical procedure for treating medically intractable Parkinson's disease and Levo-dopa induced dyskinesia. In the surgical treatment of hyperkinetic movement disorders, generalized dystonia has recently become a favorable indication of posteroventral pallidotomy. However, a commonly recognized surgical procedure for treating choreiform movement disorders has not yet been established.
