A case of postvaricella cerebral angiopathy with a good outcome in a child.

Cerebral vasculopathy is a serious but uncommon complication of varicella-zoster-virus (VZV) infection. Diagnosis is based on a recent history of VZV infection, signs and symptoms of transient ischemic attack or stroke, and vascular anomalies on neuroimaging. We report a case of postvaricella cerebral angiopathy in a 5-year-old child, who was admitted after three episodes of transient right hemiplegia, each one lasting a few minutes. He had contracted chicken pox, the month prior to admission. Brain magnetic resonance imaging showed hyperintense signals in the left lenticular and caudate nuclei, which can be considered to be a result of vasculopathy.
