Abstract:
The dizziness associated with paraneoplastic neurologic syndrome is hard to diagnose clinically because the prevalence of disease is rare, and radiologic and serologic examination result may come out normal. Opsoclonus-myoclonus symdrome is a representative of classical paraneoplastic neurologic syndromes. In this paper, we report 2 cases of paraneoplastic neurologic syndromes with negative serologic auto-antibody test and no brain lesion on MRI. Both cases were eventually diagnosed through PET. Patients with opsoclonus-myoclonus type nystagmus should be evaluated for paraneoplastic neurologic syndrome even if their radiologic and serologic findings are normal.
