Fetal gallstones: sonographic and clinical observations

Fetal gallstones were visualized sonographically in two cases at 30 and 37 weeks' gestation; follow-up scans at 2 and 3 months, respectively, disclosed their spontaneous resolution. The hypotheses advanced to explain the formation of echogenic material in the fetal gallbladder are reviewed, and the clinical utility of postnatal long-term sonographic follow-up is stressed.
