An Unusual Cause of Fetal Stroke: Secondary HSV Infection.

Herpes simplex virus (HSV) is a recognized cause of neonatal infection, with hematologic vertical spread usually only during a primary infection. This is an unusual case with hematologic spread of an HSV 2 infection resulting in a fetal stroke, not associated with a primary outbreak during pregnancy. A 25-year-old multigravida at 26 weeks was diagnosed with a large fetal stroke.
