Low-dose interleukin-2 as a novel therapeutic option for refractory paraneoplastic neurologic syndrome: a case of chronic relapsing anti-Ma2/Ta paraneoplastic myeloradiculopathy.

Abstract

Paraneoplastic neurologic syndromes (PNS) caused by anti-Ma2/Ta antibodies have diverse presentations. Myeloradiculopathy is one anti-Ma2/Ta-associated PNS manifestation. We report the case of a patient with chronic relapsing anti-Ma2/Ta paraneoplastic myeloradiculopathy. The patient was successfully treated with low-dose human recombinant interleukin-2, despite having chronic relapsing symptoms and a refractory response to conventional immunotherapy.
