Left hand apraxia is known as a unique symptom of callosal apraxia, but lower limb symptoms are rarely mentioned. We report a patient who experienced left ideomotor apraxia affecting both the upper and lower limbs after a stroke in the territory of the right anterior cerebral artery. His spontaneous gait was normal, but he was unable to move his left leg intentionally either by verbal command or by imitation. His leg symptoms gradually improved over time. We evaluated the change in cerebral blood flow in this patient using single-photon emission computed tomography. The results showed an increase in blood flow in the posterior corpus callosum; therefore, we suggested that the callosal pathway might contribute to left leg as well as left hand volitional movement.
左手失用症是胼胝体失用症的一个独特症状，但下肢症状很少被提及。我们报告了一例患者，他在大脑前动脉右侧区域发生中风后，同时出现了上肢和下肢的左侧意念运动性失用症。他的自发步态正常，但无论是口头命令还是模仿，他都无法有意移动左腿。他的腿部症状随着时间的推移逐渐改善。我们使用单光子发射计算机断层扫描评估了该患者的脑血流变化。结果显示胼胝体后部的血流量增加；因此，我们认为胼胝体通路可能有助于左下肢和左手的随意运动。
