Spatial and temporal disease progression of adult-onset subacute sclerosing panencephalitis.

ABSTRACT

An adult-onset case of subacute sclerosing panencephalitis with occipitofrontal spread of the infection documented clinically and by MRI is reported. Autopsy revealed numerous intranuclear viral inclusions and widespread demyelination in both frontal lobes. In the occipital lobes where the disease started 5 years previously, inclusions were rare, but degenerative tissue changes were prominent. This case underlines the importance of measles virus migration for the progression of this fatal disorder.
