RESUMEN
Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder. The pathogenesis is thought to be immune-mediated. In adults, it may be idiopathic or paraneoplastic in origin. However, most cases of paraneoplastic OMS in adults are not associated with well-characterized antibodies, except for a small subgroup who have anti-Ri antibodies. Herein, we provide the first detailed description of a case of OMS associated with a Kelch-like protein-11 antibody, a newly discovered biomarker for paraneoplastic neurological syndromes associated with germ-cell tumors. This was a young female patient in whom no tumor was ever detected and who had an excellent response to rituximab.
