Abstract
Subacute cerebellar degenera also known as paraneoplastic cerebellar degeneration, is one of the typical neurological lesions caused by
paraneoplastic neurological syndrom. It is caused by changes in the immune response. A case of tumor-negative anti-Yo antibody-positive
subacute cerebellar degeneration is reported to strengthen clinicians’ understanding of the disease. Early diagnosis of subacute cerebellar
degeneration is essential to improve patient survival and quality of life.
