Anomalies of placental growth with respect to its shape have been associated with adverse pregnancy outcomes. A very rare form of 'H' bilobate placental partition was observed in a 31-year-old woman presenting at 24 weeks of gestation. This observation was made during a routine obstetrics scan. Sonographic features showed that it was a non-fibroid partition. The placenta featured anterior and posterior portions separated by a large middle, vertical portion. The placenta was antero-posterior semi-circumferential in shape, measuring approximately 16.70 cm in length and 12.48 cm at shorter chorionic plate (minor axis). The middle, vertical part of the placenta partitioned the uterine cavity into two, creating the impression of two separate gestational sacs. The fetus was located in one of these. The patient was eventually delivered through caesarean section at gestational age (GA) of 36 weeks 6 days. The baby had a low birth weight of 1.70 kg. The early detection of this placental anomaly underlines the importance of ultrasonography in obstetrics.
