[Delayed-type 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 immunocompromised 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.
