Diagnostic usefulness of high resolution cross sectional MRI in symptomatic middle cerabral arterial dissection.

Dissection of the middle cerebral artery (MCA) is less frequent compared with dissection of the vertebrobasilar system or carotid artery. Recently, high-resolution cross sectional MR imaging (HRMRI) has emerged as a potential technique for atherosclerotic plaque imaging in MCA. We introduce the findings of HRMRI in a 56-year-old woman with traumatic MCA dissection. HRMRI showed an intimal flap and tapered pseudolumen with intraluminal hemorrhage. We performed stent deployment about MCA dissection after failed medical treatment. Three months later, there was no in-stent restenosis and no further neurological deficit were noted.
