Dissection of the middle cerebral artery (MCA) is less frequent compared with dissection of vessels in the vertebrobasilar system or dissection of the carotid artery. High-resolution cross-sectional magnetic resonance imaging (HRMRI) has emerged as a potential technique for atherosclerotic plaque imaging in MCA. We enrolled 3 patients with MCA dissection on whom HRMRI was performed for evaluation of MCA stenosis. Two patients had an embolic infarction in the MCA territory and focal dissection. One patient had a massive infarction in the MCA territory and long-segment dissection of the MCA. On HRMRI, our objectives had an intimal flap with patency of the lumen and 1 had extensive hemorrhaging in the false lumen.
与椎基底动脉系统血管夹层或颈动脉夹层相比，大脑中动脉（MCA）夹层相对少见。高分辨率横断面磁共振成像（HRMRI）已成为一种用于MCA动脉粥样硬化斑块成像的潜在技术。我们纳入了3例接受HRMRI检查以评估MCA狭窄的MCA夹层患者。2例患者在MCA供血区发生栓塞性梗死并伴有局灶性夹层。1例患者在MCA供血区发生大面积梗死并伴有MCA长节段夹层。在HRMRI上，我们的研究对象中有1例存在内膜瓣且管腔通畅，1例在假腔内有广泛出血。
