“Non-classical” paraneoplastic neurological syndromes associated with well-characterized antineuronal antibodies as compared to “classical” syndromes - More frequent than expected

The so-called “non-classical” PNSs in association with well-characterized onconeural antibodies were more common in our patient population than expected. Therefore, in neurological disorders of unclear etiology with a subacute onset and atypical presentation further diagnostic work-up including investigation of onconeural antibodies is necessary.
