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.
一名40岁的亚洲女性出现了由对侧鞍结节脑膜瘤引起的罕见局灶性手部肌张力障碍病例。磁共振成像显示肿瘤压迫了尾状核、豆状核、大脑脚、内囊以及基底节周围的大部分白质。通过经颧弓截骨的额颞入路将肿瘤整块完全切除，局灶性手部肌张力障碍得以治愈。术后磁共振成像显示周围脑组织的压迫已解除。该病例表明，由轴外脑肿瘤引起的继发性局灶性手部肌张力障碍可通过手术切除治愈。
