MR imaging of herpes simplex type 1 encephalitis in infants and young children: a separate pattern of findings.

OBJECTIVE
We sought to identify the initial MR findings of herpes simplex encephalitis in infants and young children.


CONCLUSION
MR imaging findings of herpes encephalitis in infants and young children appear to differ from those seen in neonates, older children, and adults. Appreciation of this MR imaging pattern coupled with a strong clinical suspicion of herpes helps to ensure the correct diagnosis is made.
