Sonographic examination of the gallbladder in two patients with preeclampsia and right upper quadrant pain demonstrated notable thickening of the gallbladder wall. The sonographic abnormality and clinical symptoms completely resolved after delivery and/or medical management of the preeclampsia. This finding is probably secondary to the hypoalbuminemia characteristic of preeclampsia and should not be mistaken for intrinsic gallbladder disease.
