Abstract

This report describes a case of large-cell lung carcinoma with neuroendocrine features, presenting with the full clinical picture of paraneoplastic opsoclonus–myoclonus syndrome. The patient had an unexpectedly dramatic resolution of the neurologic dysfunction after receiving antineoplastic treatment. Symptom improvement paralleled a progressive decline of serum ANNA-2 antibody titers to undetectable levels.
