 A case of focal cerebral arteriopathy-inflammation in a 9-year-old girl. (A) Axial diffusion-weighted image on admission, showing an acute infarct involving the basal ganglia in the lenticulostriate artery territory. (B) Digital subtraction angiography of the left internal carotid artery (ICA) 7 days after admission, showing irregular stenosis with a banding pattern from the distal ICA to the middle cerebral artery (MCA) and occlusion of the anterior cerebral artery (ACA). (C) Magnetic resonance angiography (MRA) on admission, showing slight stenosis from the ICA to the MCA and ACA (arrow). (D) MRA at 29 days after onset, showing worsened stenosis from the distal ICA to MCA and occluded ACA (arrow). (E) MRA at 12 months after onset, showing improvement of the internal caliber from the ICA to the MCA and ACA (arrow)
