Chickenpox and stroke in children: case studies and literature review

Postvaricella cerebral arteriopathy (PVCA) presents with acute haemiparesis and/or haemidistonia, caused by ischaemic lesions of internal capsule and/or basal ganglia, related to stenosis of proximal middle and/or anterior cerebral arteries. Anti-aggregant drugs are recommended to prevent thrombus expansion and recurrent stroke, but neurologic outcome is usually good regardless of the therapeutic approach. Conclusion Chickenpox should be considered in differential diagnosis of ischaemic stroke in healthy children who fit the clinical and radiological typical profile of PVCA.
