title: Case of stroke in a 7-year-old male after parvovirus B19 infection.
abstract: A 7-year-old male presented sudden-onset left hemiparesis, left-sided paresthesia, central paralysis of the left VII cranial nerve, and subsequent headache. Magnetic resonance scans were obtained 24 hours after admission. T(2)-weighted images disclosed hyperintensities located mainly in the posterior portion of the lenticular nucleus and in the head and body of the right caudate nucleus. A diagnosis of ischaemic stroke was made on the basis of neuroradiologic findings. Laboratory tests undertaken to establish the cause of stroke revealed parvovirus B19 infection preceding the neurologic abnormalities. In the absence of other known risk factors for stroke the possibility of parvovirus B19's being correlated with stroke onset is discussed.
