This case is a good example of how viral encephalitis is occasionally aggressive and destructive of the brain tissue. Within less than one month, encephalomalacia, cortical laminar necrosis, and cerebral atrophy develop with a subsequent permanent disability
Cortical laminar necrosis is usually described in cases of cerebral infarction and metabolic diseases, however, it is also reported in patients with encephalitis 1
In this case, the preceding gastroenteritis and the CSF analysis results were highly suggestive of viral encephalitis.
