Subacute measles encephalitis

Introduction. We analyze the clinical, neurological, EEG, neuroradiological features and evolution of two patients with subacute measles encephalitis. Case reports. The patients, aged five years and eleven months respectively showed an acute, progressive neurological compromise and deterioration of consciousness, epilepsia partialis continua and progressive damage on neuroimaging, with a history of measles in the first case and exposure to the virus in the second. The first patient had Hodgkin's disease and the other had a familial C4 deficit disorder. Fundoscopic examination showed lesions on the retina. The EEG showed unilateral slow waves and spikes. Brain CT and MRI revealed progressive cerebral atrophy and a unilateral corticosubcortical lesion. Measles antibodies in CSF were found in the first child and oligoclonal bands in the second. Our first patient died after three months and the second has a severe neurological damage. Conclusion. In immunocrompromised patients with the exposure to a history of measles, acute neurological compromised and deterioration of consciousness, epilepsia partialis continua and progressive damage on neuroimaging, subacute measles encephalitis should be considered.
