The evaluation showed the positivity of Anti Yo Antibody in her and on extensive evaluation, she was found to be having a lymph node metastasis from a probable ovarian malignancy without the evidence of the primary in the ovary.

Keywords: Paraneoplastic cerebellar degeneration, Anti Yo antibody, lymph node metastasis.
