Abstract
Background
Herpes simplex virus (HSV) encephalitis is a rare association with pediatric neurosurgical pathologies.
Case report
A 13-year-old boy was diagnosed with an inoperable, biopsy-proven pontine grade II astrocytoma. During radiotherapy, he developed status epilepticus controlled by thiopentone with intubation and ventilation. Empiric cefotaxime and aciclovir were given. Lumbar cerebrospinal fluid (CSF) showed a normal white cell count, normal glucose, and a slightly elevated protein level. However, the CSF showed a positive polymerase chain reaction (PCR) for HSV type 1 DNA. Intravenous aciclovir was given for 21 days and foscarnet for 7 days. He was extubated after 4 weeks at which time he was aphasic with spastic diplegia. After 8 weeks, MRI brain scan showed the typical bitemporal pattern of HSV encephalitis. He made slow improvement but died 8 months after diagnosis from tumor progression.
Conclusion
HSV encephalitis is a rare but life threatening complication in neurosurgical patients. A low threshold for both investigation with CSF PCR and empirical treatment with intravenous aciclovir is warranted. As in this case, initial microscopic examination of the CSF may be normal. The literature on HSV encephalitis in neurosurgical patients is discussed.
