Extralobar pulmonary sequestration（ELS）accounts for 25％ of all sequestrations, and intraabdominal ELS is rare with 10-15％. A 29-year-old multipara woman was reffered to our hospital for further evaluation of a fetal left subdiaphragmatic mass at 27 weeks’ gestation. A well circumscribed and hyperechogenic intraabdominal suprarenal mass was detected on prenatal ultrasonography（US）. Magnetic resonance imaging（MRI）at 33 weeks’ gestation revealed well-defined mass with homogenious high-signal intensity being similar to normal lung. A combination of color and power Doppler US at 35 weeks’ gestation allowed visualization of a vessel arising from the descending aorta and supplying the mass. These results of imaging studies favored an ELS. A 2,904g male infant was vaginally delivered at 39 weeks’ gestation, and asymptomatic at birth. After follow-up on the outpatient department, laparoscopic resection was undergone at 1 year old. Fetal intraabdominal ELS was often found as suprarenal mass. Combination of US and MRI allows a more accurate diagnosis, and therefore it’s made possible to give counseling and manage more effectively.
