胼胝体梗死所致的发作性拮抗性失用

Paroxysmal diagonistic ideomotor apraxia in ischemic infarction of the corpus callosum

目的探讨胼胝体梗死引起拮抗性失用的特点和机制。方法对1例表现为发作性拮抗性失用的患者，分别进行神经心理、头颅磁共振、颈cT血管成像检查。结果神经心理检查提示为拮抗性失用，头MRI示右侧胼胝体梗死，予抗血小板，改善脑循环治疗后发作减少。结论胼胝体梗死可以引起发作性拮抗性失用为特征的神经心理症状。

Objectives To report the clinical features and treatment in a case with paroxysmal diagonistic ideomotor apraxia after ischemic infarction of the corpus callosum. Methods The neuropsyehological tests, brain MRI, the TCD and carotid duplex sonography were carried out in the patient who is right handed and had had presentation of paroxysmal diagonistic ideomotor apraxia for ten days. Results Neuropsychologicai tests confirmed the diagnosis of paroxysmal diagonistic apraxia in this patient. MRI showed isehemic infarction in the right corpus eallosum.
