A physical examination of our patient on admission revealed lucid consciousness, a body temperature of 36.5°C, blood pressure of 116/85mmHg, and pulse rate of 75 beats per minute. She had mild abdominal pain and her uterus was painfully tender. On abdominal ultrasonography, the fetus had a cephalic presentation, and no heartbeat was observed. Her placenta was attached to the anterior wall, and a 9.5×4.6cm internal retroplacental hematoma was observed (Figure 2). Echo-free space suggesting uterine rupture or other intra-abdominal hemorrhage was not present. A pelvic examination revealed no vaginal hemorrhage and a cervical os dilation of 3cm. Effacement was 60%, and station was -2 (Bishop score: 7). Uterine contractions were three minutes apart according to cardiotocography.
