    Abstract

    We present three patients with a circumvallate placenta diagnosed by two-dimensional (2D)/three-dimensional (3D) ultrasound and HDlive early in the second trimester of pregnancy. The characteristic 2D sonographic findings were a thick placenta with its edges protruding into the uterine cavity. The unique 3D ultrasound characteristic of a circumvallate placenta early in the second trimester is a pizza-like appearance. Moreover, 3D ultrasound and HDlive can clearly differentiate partial from complete circumvallate placentas. Three-dimensional ultrasound and HDlive provide additional, useful information for the early second-trimester diagnosis of a circumvallate placenta.
