Acute acalculous cholecystitis in systemic lupus erythematosus: a case report and review of the literature.

A 27-year-old woman with systemic lupus erythematosus (SLE) was found to have acute acalculous cholecystitis. At the time of admission, the patient was not under corticosteroid or immunosuppressive therapy. Computed tomography (CT) and ultrasonography revealed findings in the gall bladder consistent with acute acalculous cholecystitis. Her abdominal pain completely disappeared following corticosteroid therapy, with dramatic improvement in the images of CT and ultrasonography. Six similar cases of SLE complicated with acute acalculous cholecystitis have been reported in the literature and they were all treated surgically by cholecystectomy or cholecystostomy. This is the first case report in which acute acalculous cholecystitis accompanying SLE was treated successfully by corticosteroid without surgical intervention.
