Pulmonary artery sling is a rare congenital vascular anomaly. Partial anomalous left pulmonary artery is even rarer and no in utero observation has yet been reported. Here, we present the ultrasonographic findings of a 38-year-old woman at 32 weeks of gestation whose fetus showed a normal bifurcation of the pulmonary trunk into the right and left pulmonary arteries, but an anomalous origin of the left lower lobe pulmonary artery from the right pulmonary artery. These findings were confirmed by postnatal echocardiography and thoracic computed tomography.
