Severe stenosis in the lower trunk of the left middle cerebral artery (MCA). (A) Magnetic resonance imaging (MRI) showed bead-like high intensity lesion near the ventricular body. (B) MRI angiography revealed severe stenosis in the lower trunk of the left MCA (small arrow) and an aneurysm (large arrow) at the anterior communicating artery. (C) Nine days after admission, the symptoms were aggravated and the second MRI scan demonstrated increased infarction area. (D) Perfusion imaging showed that greater time is needed for the blood flow to reach the left parietal occipital lobe. E&F. Digital subtraction angiography demonstrated severe stenosis in the lower trunk of the left MCA (arrow, E), and stent angioplasty was performed with an Enterprise stent to relieve the stenosis (F). G. Endovascular coil embolization was performed to completely occlude the anterior communicating aneurysm. (H). Follow-up angiography at six months following stenting revealed patent flow in the lower trunk of the left MCA. (I). Perfusion imaging showed the time is significantly improved for the blood flow to reach the left parietal occipital lobe.
