Periaortitis Associated with Anti-neutrophil Cytoplasmic Antibodies Induced by Bevacizumab Combination Therapy

Drug-induced vessel vasculitis is a rare complication of chemotherapy. In particular, few reports have investigated drug-induced large vessel vasculitis. We herein report the case of a 57-year-old woman with advanced lung adenocarcinoma who developed perinuclear anti-neutrophil cytoplastic antibodies (p-ANCA)-positive periaortitis induced by bevacizumab combination chemotherapy. With the increasing use of combination therapy with bevacizumab, the incidence of vascular complications will potentially increase. A noninfectious fever occurring during chemotherapy might be a sign of vasculitis; therefore, we must ensure that possible periaortitis is not overlooked.
