title: Focal hand dystonia cured by removal of clinoid meningioma-case report-.
abstract: A 40-year-old Asian female presented with an unusual case of focal hand dystonia caused by contralateral clinoid meningioma. Magnetic resonance imaging showed that the tumor compressed the caudate nucleus, lentiform nucleus, cerebral peduncle, internal capsule, and a large portion of the white matter surrounding the basal ganglia. The tumor was gross totally removed via a frontotemporal approach with zygomatic osteotomy, resulting in cure of the focal hand dystonia. Magnetic resonance imaging after surgery showed that the compression of the surrounding brain was released. This case shows that secondary focal hand dystonia caused by extra-axial brain tumor can be cured by surgical removal.
