title: Stroke after varicella vaccination.
abstract: Two children presented with acute hemiparesis 5 days and 3 weeks following varicella vaccination. Both showed unilateral infarction of the basal ganglia and internal capsule, a distribution consistent with varicella angiopathy. Both children had small patent foramen ovale (PFO), and one child also had severe iron-deficiency anemia, which may have predisposed the patient to this adverse effect.
