Left pulmonary artery (LPA) sling is a very rare congenital anomaly. This anomaly is often associated with tracheal narrowing caused by either intrinsic stenosis or malformation of tracheal rings. To the present authors’ knowledge, prenatal diagnosis of LPA sling has not been reported frequently, and three-dimensional ultrasound was not used in any of the previous cases. The aim of this article is to report one case of LPA sling, which was diagnosed in a fetus at 24 weeks gestation by routine echocardiography and four-dimensional spatio-temporal image correlation (STIC), with focus on the particularity of this rare anomaly prenatally diagnosed.
