Anti-Yo paraneoplastic cerebellar degeneration (PCD) is a rare autoimmune neurological syndrome characterised by cerebellar symptoms and frequently associated with gynaecological malignancies. While typically preceding the diagnosis of the malignancy, rarely it may present later in the disease course, heralding a recurrence prior to biochemical or radiological confirmation. Disease management is challenging and prognosis remains poor.
We present the case of a woman with stage IV ovarian adenocarcinoma who developed anti-Yo PCD 16 months post malignancy diagnosis while receiving bevacizumab maintenance therapy. We review the literature and outline the difficulties in diagnosis and the frequently refractory nature of PCD to available treatments.
