Subacute sclerosing panencephalitis after drug-induced immunosuppression

A girl developed subacute sclerosing panencephalitis (SSPE). Eight years earlier she had had measles infection contracted shortly after cytotoxic treatment and radiotherapy for a spinal neuroblastoma. The case illustrates that typical SSPE, like immunosuppressive measles encephalopathy, can arise after drug-induced immunosuppression, and supports the view that these diseases probably represent opposite ends of a spectrum induced by measles virus infection in an individual with some form of immunological deficiency.
