[Paraneoplastic opsoclonus]

Abstract

Opsoclonus occurs in a number of clinical settings, but its association with carcinomas in adult patients is rare. We present a case of paraneoplastic opsoclonus in a 63 year-old male who had a small-cell lung cancer. Even though paraneoplastic opsoclonus may be associated with an immunological response, there was no elevation of blood parameters associated with inflammation. The patient was treated with prednisolon without any clinical effect, and died only a few months after opsoclonus was diagnosed.
