Two cases of the sonographic demonstration of yolk sac calcification associated with first-trimester intrauterine embryonic demise are reported. Histologic verification was obtained in one case. Yolk sac calcification may reflect typical dystrophic changes or be more specifically related to a yolk sac calcium-binding protein. Awareness of this sonographic finding - which the authors believe to be previously undescribed - may prevent diagnostic errors.
