Summary: A 35-year-old pregnant woman was referred to our institution at 33 weeks’ gestation for evaluation of a fetal abdominal tumor. B-mode ultrasonography demonstrated a massive lesion. Bidirectional power Doppler mode showed abundant blood flow surrounding the tumor. On superb micro-vascular imaging, various Doppler signal patterns were observed within the tumor, including diffuse fine dotted-like signals, linear flow, and internal shunt flow. Sequential observations of the tumor and cardiac cycles also revealed pulsatile flow beneath the edges of the tumor and continuous fine flow in the central area, resembling a ‘centripetal fill-in’ appearance on contrast computed tomography. Therefore, we assumed the fetal tumor to be a hepatic hemangioma. Fetal heart failure was detected at 37 weeks’ gestation, and a 2,484-g female infant was delivered with 1- and 5-min Apgar scores of 7 and 8, respectively. A postnatal contrast computed tomography examination showed a progressive centripetal fill-in appearance, leading to a diagnosis of hepatic hemangioma. Kasabach-Merritt syndrome was also noted. Intensive treatment was performed, and the infant was discharged at 3 months after birth. In summary, we experienced a case of hepatic hemangioma diagnosed in utero using superb micro-vascular imaging. And basing seamless postnatal treatments on prenatal imaging findings may help to reduce the perinatal mortality.
