Half of the patients with SLE experience gastrointestinal symptoms, with the most common being nausea, vomiting, anorexia, and abdominal pain. Mesenteric vasculitis is a severe and rare complication of SLE and one of the most frequent causes of severe acute abdominal pain. The authors present a case of a 57-year-old woman with SLE who was diagnosed with necrotizing mesenteric vasculitis following a urinary septic shock. The patient was treated with high-dose corticosteroid therapy and cyclophosphamide, with resolution of the clinical picture.engDoenças Gastrointestinais/complicaçõesLúpus Eritematoso SistémicoLesões do Sistema VascularVasculitesGastrointestinal DiseasesLupus Erythematosus, SystemicVascular System InjuriesVasculitisjournal article
