Abstract

Junliang Yuan, Zejin Jia, Wei Qin, Wenli HuDepartment of Neurology, Beijing Chaoyang Hospital, Capital Medical University, Beijing 100020, People’s Republic of ChinaAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a group of inflammatory disease involving the central nervous system. Although most commonly an idiopathic autoimmune condition, NMOSD may also occur as a paraneoplastic syndrome in rare instances. Herein, we report a rare case of a 60-year-old woman with paraneoplastic NMOSD associated with breast cancer. Our findings increase the recognition that NMOSD may present as a paraneoplastic neurological syndrome associated with breast cancer. Our case also raises awareness of an important complication of neurological complications of breast cancer. Early diagnosis of paraneoplastic NMOSD may be imperative for a better prognosis.Keywords: neuromyelitis optica spectrum disorder, paraneoplastic syndrome, breast cancer
