Paraneoplastic Cerebellar Degeneration Associated with Pelvic Liposarcoma: A Rare Case Report.

Paraneoplastic cerebellar degeneration (PCD) is one of the most common paraneoplastic neurological syndromes characterized by the rapid development of severe cerebellar ataxia. In this report, a 23-year-old female with noticeable dizziness and gait instability was described. The enhanced CT scanning suggested the presence of a pelvic tumor. Then, PCD was established. Postoperative pathological result defined it as a liposarcoma (LS) with dedifferentiation. Interestingly, clinical symptoms disappeared after the surgical removal of the pelvic tumor. To our knowledge, this was the first case report with PCD due to LS.
