Anti-Yo-associated paraneoplastic cerebellar degeneration in a man with gastric adenocarcinoma: one case report and literature review / 中华神经科杂志

ABSTRACT

A male patient of acute onset is reported, whose main clinical manifestations were ataxia and dysarthria, with elevated carcinoembryonic antigen, non-small cell lung cancer antigen, carbohydrate antigen 72-4, positive anti-Yo antibody. The patient′s gastroscopy and biopsy result suggested gastric cancer, and his symptoms got better after radical surgery. Anti-Yo-associated paraneoplastic cerebellar degeneration complicated with gastric adenocarcinoma was diagnosed. If encountering cases of ataxia or dysarthria in clinical work, the possibility of paraneoplastic cerebellar degeneration should be considered and evidence for tumor should be searched, so as to avoid missed diagnosis or misdiagnosis.
