自发性颈头动脉夹层是一种罕见的中风原因[1]。大脑中动脉（MCA）的节段很少受累，据报道，日本自发性颈头动脉夹层的MCA夹层（MCAD）发生率为4%[2]。先前的报告表明，磁共振成像（MRI）可能有助于检测颅内椎基底动脉夹层[3]，尽管在MCAD患者中的适用性尚不清楚。在这里，我们报告了一个病人谁有MCAD的特征性病变，这是证明了高分辨率T1加权3D图像获得使用3特斯拉MRI（3T MRI）系统。
Spontaneous cervicocephalic arterial dissection is an uncommon cause of stroke [1]. Segments of the middle cerebral artery (MCA) are rarely involved, and the incidence of MCA dissection (MCAD) is reported to be 4% of the spontaneous cervicocephalic arterial dissections in Japan [2]. A previous report suggests that magnetic resonance imaging (MRI) may be useful for detecting intracranial vertebrobasilar artery dissection [3], although the applicability in MCAD patients is unknown. Here, we report a patient who had MCAD with characteristic lesions, which was demonstrated by high-resolution T1-weighted 3D images obtained using a 3-tesla MRI (3T MRI) system.
