We report here a 1-year-old boy with human herpesvirus 6 (HHV 6) -associated encephalopathy. On the 3rd day of fever, he had a generalized tonic seizure followed by mild disturbance of consciousness, which recovered completely the next day. Two days later, he had skin rash of exanthema subitum, and his consciousness declined frequently. EEG demonstrated rhythmic wave bursts originating from central areas bilaterally, followed by a generalized spike-and-wave complex which was associated with disturbed consciousness. We made the diagnosis of a status of complex partial seizures. Because the focal discharge on ictal EEG, MRI was performed. In the subcortical white matter of the frontal-parietal lobes, there were high signals on diffusion-weighted MRI, the apparent diffusion coefficient of which was much lower than that of normal controls. The affected areas soon disappeared with improvement of clinical symptoms. The transient MRI findings may indicate reversible cytotoxic brain edema. He showed no neurological sequelae as yet.

The mechanisms underlying the Hemiconvulsion-Hemiplegia-Epilepsy syndrome remains unclear. The current proposed pathogenic mechanism is a neuronal injury induced by venous thrombosis and/or hypoxia. Children develop hemispheric brain atrophy with contralateral hemiplegia, epilepsy, and a variable degree of cognitive deficit. We report a 33 months old female child a case of hemiconvulsion-hemiplegia-epilepsy syndrome with right hemisphere unilateral brain edema and left sided hemiplegia and aphasia who presented with left upper extremities complex partial seizures with generalization to tonic clonic seizures and developed status epilepticus that posed diagnostic and therapeutic challenges. Progressive atrophy of the right cerebral hemisphere was noted after 3 months of follow up. Hemiconvulsion-Hemiplegia-Epilepsy syndrome should be suspected in a child with unilateral cerebral hemisphere brain edema and hemiplegia with cognitive deficit following status epilepticus to provide patients and families with an accurate prognosis regarding the subsequent development of epilepsy.
