Anti-titin reactive Paraneoplastic Cerebellar degeneration with thyroid papillary cancer

Paraneoplastic neurogenic disorders are syndromes caused by an autoimmune pathogenesis against ‘onconeural antigens' shared between a tumor and the nervous system. They are rare but important and can cause severe neurologic disability if not recognized and treated early. Here we describe the first reported case of anti-titin reactive cerebellar syndrome as paraneoplastic phenomenon in association with papillary thyroid carcinoma without myasthenia gravis.
