Atypical Subacute Sclerosing Panencephalitis With Short Onset Latency.

An 11-month-old boy presented with focal seizures, myoclonic jerks and altered sensorium of one month duration, with a history of measles at eight months of age. A diagnosis of Subacute sclerosing panencephalitis (SSPE) was made on the basis of typical EEG changes and presence of anti-measles antibody in cerebrospinal fluid. A differential diagnosis of SSPE should be considered in all forms of acute encephalopathy in infants for early diagnosis and management.

Acute bilateral vision loss as the presenting feature of subacute sclerosing panencephalitis.

A 12-yr-old boy with an atypical presentation of subacute sclerosing panencephalitis (SSPE) is described. Bilateral macular chorioretinitis preceded the neurological symptoms by 3 weeks. Both visual and neurological features had an acute onset. Clinicians need to be aware that macular chorioretinitis in a child may be the heralding feature of SSPE.
