Background: Peripheral neuropathy among women with ovarian dysgerminoma has not been so far reported in the literature.
Case: We report a case of an 18-year-old woman with an association of an abdominal relapse of an ovarian dysgerminoma and a polyradiculoneuritis. The normality of neurologic investigations and the disappearance of all sensitive and muscular alterations after tumor ablation and one cycle of chemotherapy are in favor of a paraneoplastic syndrome. After 5 years this young woman is still in complete remission without any neurologic symptoms.
Conclusion: We describe the first case of a polyradiculoneuritis associated with an ovarian dysgerminoma. The evolution of the paraneoplastic syndrome was favorable after treatment of the tumor.
