Anti-Ri autoimmune encephalitis associated with breast cancer

DPPX antibody-mediated autoimmune encephalitis：the first case with breast cancer and review of the literature

“…In summary, DPPX antibody-mediated encephalitis is a rare condition with atypical symptoms, often leading to potential misdiagnoses as cerebrovascular disease or other systemic disorders. Other autoimmune antibodies secondary to breast cancer such as AMPAR antibodies [ 21 ] and RI antibodies [ 22 ] have also been reported, which should be considered to make an accurate clinical diagnosis. At the same time, previous studies have only found that DPPX antibody-mediated AE is related to lymphoma, and others can not be seen.…”

CRMP5 Antibodies—Diagnostic Challenges

“…In two cases, both Hu and SOX1 antibodies appeared together with CRMP5, which is also in line with previous studies ( 3 , 11 ). Identification of other autoantibodies co-expressed with CRMP5 is important as peripheral neuropathy has also been associated with Hu and Sox1 antibodies ( 12 – 14 ) and encephalopathy with Ri antibodies ( 15 ).…”
