Movement disorders are uncommon presenting features of brain tumours. Early recognition of such lesions is important to arrest further deficit. We treated seven patients with movement disorders secondary to brain tumours over a period of seven years. Only two of these were intrinsic thalamic tumours (astrocytomas) while the rest were extrinsic tumours. The intrinsic tumours were accompanied by hemichorea. Among the extrinsic tumours, there was one pituitary macroadenoma with hemiballismus and four meningiomas with parkinsonism. Symptoms were unilateral in all patients except one with anterior third falcine meningioma who had bilateral rest tremors. There was relief in movement disorders observed after surgery. Imaging by computed tomography or magnetic resonance imaging is mandatory in the evaluation of movement disorders, especially if the presentation is atypical, unilateral and/or accompanied by long tract signs.
运动障碍是脑肿瘤不常见的表现特征。早期识别此类病变对于阻止进一步的功能缺损很重要。我们在七年时间里治疗了7例继发于脑肿瘤的运动障碍患者。其中只有2例是丘脑原发性肿瘤（星形细胞瘤），其余为继发性肿瘤。原发性肿瘤伴有偏身舞蹈症。在继发性肿瘤中，有1例垂体大腺瘤伴偏身投掷症，4例脑膜瘤伴帕金森症。除1例前1/3大脑镰旁脑膜瘤患者出现双侧静止性震颤外，所有患者的症状均为单侧。术后观察到运动障碍有所缓解。在评估运动障碍时，尤其是表现不典型、单侧和/或伴有长束征时，计算机断层扫描或磁共振成像检查是必不可少的。
