A case of female patient with recurrent diarrhea,vomiting,serous cavity effusion,who 2 seemed to responded to 2-year treatment of anti-tuberculosis,had been misdiagnosed as tuberculous peritonitis for more than 5 years.Because of recurrent upper abdominal discomfort,nausea,and vomiting for 3 days she was admitted,and a hospital-wide consultation confirmed her systemic lupus erythematosus(SLE) complicated by mesenteric vasculitis,intestinal pseudo-obstruction,incomplete ureteral obstruction,and lupus nephritis.Her disease was controlled after treatment,with no relapse.The case promotes that SLE with digestive symptoms as initial manifestations has a high rate of clinical misdiagnosis,so we must be alert to SLE when the patients have autoantibody-negative or low titer-positive with multi-system damage.
