We present a case of bilobed placenta diagnosed by HDliveFlow with the HDlive silhouette mode early in the 2nd trimester of pregnancy. A 29-year-old Japanese pregnant woman, gravida 4, para 1, was referred to our hospital based on the patient’s wish at 23 weeks and 3 days of gestation. Two-dimensional (2D) sonography showed a single live fetus with biometry consistent with the gestational age. Moreover, two separated parts of the placenta were noted at the anterior and posterior uterine walls. HDliveFlow with the HDlive silhouette mode clearly depicted two lobes of the placenta (near equal size), and the main umbilical cord attached to the periphery of the anterior part of the placenta. One large connecting vessel between these two placental parts was also clearly identified. Bilobed placenta was strongly suggested. After birth, the gross specimen of the placenta confirmed the diagnosis. HDliveFlow with the HDlive silhouette mode may be an adjunctive tool to 2D sonography to diagnose abnormalities of the placenta in utero.
