A 48-year-old female presented with vertiginous feeling and behavior disturbance. Computed tomography showed an arachnoid cyst on the left cerebral convexity. Single photon emission computed tomography revealed decreased cerebral blood flow (CBF) in the left frontal lobe. The Wechsler Memory Scale-Revised test demonstrated memory dysfunction. The arachnoid cyst was partially removed. Disturbances in CBF and behavior disappeared postoperatively. Local ischemia induced by compression due to arachnoid cyst may cause memory dysfunction and behavior disturbance. Neuropsychometric examination is useful for the evaluation of such symptoms.
一名48岁女性出现眩晕感和行为障碍。计算机断层扫描显示左侧大脑凸面有一个蛛网膜囊肿。单光子发射计算机断层扫描显示左侧额叶脑血流量（CBF）减少。韦氏记忆量表修订版测试显示存在记忆功能障碍。蛛网膜囊肿被部分切除。术后脑血流量和行为障碍消失。蛛网膜囊肿压迫引起的局部缺血可能导致记忆功能障碍和行为障碍。神经心理测量检查有助于评估此类症状。
