Systemic lupus erythematosus associated with recurrent lupus enteritis and peritonitis

We describe the case of a 41-year-old woman with systemic lupus erythematosus (SLE) who suffered from repeated reversible lupus enteritis characterized by marked edematous thickening of the small intestine. Ultrasonography (US) and computed tomography (CT) manifested as an 'accordion-like appearance' and a 'target-like appearance', respectively. Resolution of gastrointestinal tract wall thickening was observed on follow-up US performed a week after the increase in predinosolone (PSL). We conclude that careful evaluation of sonographic and radiographic findings helps to establish the diagnosis of lupus enteritis.
