INTRAUTERINE GROWTH-RETARDATION AND TRANSVERSE LIE DUE TO MASSIVE SUBCHORIONIC THROMBOHEMATOMA AND OVERLYING LARGE SUBCHORIONIC CYST

Massive subchorionic thrombohematoma (MST) is an uncommon condition bu t is associated with poor perinatal prognosis and intra-uterine growth retardation (1, 2). We report a case of MST associated with a large s ubchorionic cyst, which was complicated with intra-uterine growth reta rdation and transverse lie. We have not found a similar report which h ad serial ultrasound scan demonstrating the evolution from a mild hete rogenic echodense placental mass to a large subchorionic cyst. The pur pose of this report is to highlight the importance of early recognitio n of this condition on ultrasound scan, which might otherwise escape d etection on routine clinical examination.
