Mesenteric Vasculitis in a Case of Systemic Lupus Erythematosus.

We present a case of mesentric vasculitis with systemic lupus erythematosus who relapsed after high dose steroids but achieved subsequent remission after starting pulse cyclophosphamide therapy. 38 years old female who had earlier polyserositis and cerebral venous thrombosis was admitted with provisional diagnosis of SLE and developed acute abdominal pain during hospital stay. She was diagnosed as mesenteric vasculitis and initially responded to pulse methylprednisolone. However, she had relapse which subsequently responded to pulse cyclophosphamide and steroids. During the ward course she also developed acute thyroiditis and was diagnosed to have class IV lupus nephritis on renal biopsy.
