[Imaging diagnosis of lupus enteritis--especially about sonographic findings].

We evaluated 4 cases of lupus enteritis by US, abdominal X-ray and CT. On US examinations, in particular, we observed ascites and edematous thickening of the small intestine where Kerckring folds with submucosal edema resembled an accordion. After steroid treatment and consequent improvement of the disease, we noticed disappearance of the intestinal thickening and ascites on US examination, compatible with the diagnosis of lupus enteritis. Based on these results, US was useful for the diagnosis and follow-up of lupus enteritis.
