Child Neurology: Pediatric seizures with hyaline astrocytic inclusions.

Astrocytic dysfunction is implicated in epilepsy through many proposed molecular mechanisms, but there is also a clinicopathologic entity of epilepsy featuring astrocytic inclusions. At least 17 cases of early-onset epilepsy with eosinophilic, hyaline astrocytic inclusions have been reported since the early 1990s. Most of these cases also involve developmental delay. The diagnosis is made by neuropathologic analysis that demonstrates brightly eosinophilic, hyaline, refractile astrocytic inclusions seen under light microscopy with hematoxylin & eosin stain. We review the clinicopathologic entity of pediatric epilepsy with hyaline astrocytic inclusions and report an illustrative case.
