Abstract
Nonspecific manifestations and a varied distribution of brain lesions can delay the diagnosis of herpes simplex encephalitis (HSE) in neonates. The aim of this study was to report predominant brain lesions in neonatal HSE, and then to investigate the association between pattern of predominant brain lesions, clinical variables and neurodevelopmental outcome. A multicenter retrospective study was performed in neonates diagnosed with HSE between 2009 and 2014. Magnetic resonance (MR) images, including diffusion-weighted images, were obtained in the acute and chronic phase. Three predominant areas of brain injury could be defined based on characteristic MRI findings in 10 of the 13 infants (77%). The inferior frontal/temporal pole area was involved in five (38%) patients. The watershed distribution was present in six (46%) patients. Four (31%) infants involved the corticospinal tract area. No significant association was found between any predominant distribution of brain lesion pattern and sex, country, viral type or viral load. However, the corticospinal tract involvement was significantly associated with motor impairment (P=0.045). Three predominant areas of brain lesion could be recognized in neonatal HSE. Recognition of those areas can improve prediction of neurodevelopmental outcome.
