Acute encephalopathy in childhood is frequently associated with common infections, especially in East Asia. Various types have been identified although many cases remain unclassified. Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease presenting impairment of cortisol biosynthesis. We report three CAH children with acute infection-related encephalopathy. They exhibited disturbed consciousness or seizures, which did not improve after glucocorticoid administration, accompanied by clinical and laboratory findings of adrenal insufficiency. Brain MRI disclosed various patterns of white matter lesions, suggesting different types of acute encephalopathy such as clinically mild encephalitis/encephalopathy with a reversible splenial lesion or hemiconvulsion-hemiplegia syndrome. Acute encephalopathy should be considered and brain MRI immediately performed when impairment of consciousness does not improve after intravenous glucocorticoid administration in CAH patients. Further research is required to elucidate the epidemiology and pathogenic mechanisms of acute encephalopathy in CAH.

Hemiconvulsion-Hemiplegia (HH) syndrome represents an uncommon consequence of prolonged unilateral clonic or hemiconvulsive status epilepticus in childhood, usually occurring during a febrile illness, followed by ipsilateral hemiplegia. The subsequent appearance of focal seizures configures the so called Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome. The pathogenesis of HH/HHE syndrome is still unclear. We describe the case of a 4 year-old girl with congenital adrenal hyperplasia (CAH) whom developed HH/HHE syndrome with drug resistant seizures at the age of 21 months and underwent left cerebral hemispherotomy at the age of 3 years and 6 months. Histopathological findings showed the presence of an underlying inflammatory-degenerative process. Disregulation of the inflammatory cascade has been proposed as one of the possible pathogenetic mechanisms underlying HH/HHE syndrome. To our knowledge however, this is the first report of an association with a histologically documented inflammatory process. The clinical and histopathological findings of our reported case lend support to the possible role of inflammation in the pathogenesis of HH/HHE syndrome.
