Combined Cerebellar and Spinal Cord Deficits Caused by anUnderlying Gynecologic Malignancy

Paraneoplastic cerebellar degeneration (PCD) is an uncommon autoimmune disorder targeting antigens within the nervous systemand is usually associated with an underlying malignancy. Neurologic symptoms frequently precede the cancer diagnosis, which ismost often seen in women with breast or gynecologic tumors. Anti-Yo-related PCD is the most common PCD syndrome, and oneof the best understood. Although cerebellar signs are characteristic of anti-Yo PCD, myelopathy is an unusual presentation of anti-Yo PCD based on published case series and reports. Unfortunately, the prognosis for anti-Yo PCD is often poor, and most patientsbecome bedridden. We report a case highlighting a severe presentation of cerebellar degeneration along with an unusualfinding ofmyelopathy in a patient with a newly diagnosed gynecologic cancer.
