SUBACUTE SCLEROSING PANENCEPHALITIS Figure 3-32 SUBACUTE SCLEROSING PANENCEPHALITIS Multiple white matter oligodendrocytes contain typical violaceous intranuclear inclusions (arrows). Note the absence of cytoplasmic inclusions (inset). These viral inclusions should not be confused with those in p...

JC VIRUS Figure 3-37 JC VIRUS This virus reaches the CNS via a hematogenous route and early lesions are maximal at the gray-white matter junction. In later stages of disease, as seen here at autopsy, the demyelinating lesions coalesce and form large, partially cavitated lesions (at right and top)...
