Magnetic resonance imaging differential diagnosis of brainstem lesions in children

Figure 1 Pontine ischemic infarct. A 2-year-old girl shows a large median and left paramedian T1 hypointense (mid-sagittal image in panel A) and T2 hyperintense (axial images in panels B and C) lesion as lacunar sequela of an infarct in the territory of basilar artery perforators. Time of flight maximum intensity of projection images (panels D and E) show residual segmental sub-occlusive stenosis of the basilar artery (white arrow in D and E).
