Color Doppler ultrasound is one the common methods of screening for this condition, but its diagnostic accuracy can be affected by the position of the placenta, the shape of the pregnant woman&rsquo;s body, and whether the fetus is oriented in an open or closed position. Magnetic resonance imaging has the advantages of high soft tissue resolution and wide field of vision, which facilitate objective and comprehensive evaluation of fetal development. It can be an important supplementary means of prenatal screening. We here report a case of fetal bilateral lip angle asymmetry revealed by color Doppler ultrasound screening at 26 weeks&rsquo; gestation. Magnetic resonance image negative interval scanning was used to diagnose transverse facial cleft, which was confirmed after induced labor. We also retrospectively analyzed the process of embryonic development, imaging manifestations, and treatment methods of transverse facial cleft.</span></span></span></span></span></span></span></span></span></span></div> Fetus, transverse facial cleft, magnetic resonance imaging, diagnosis. 259 262 http://ijrr.com/browse.php?a_code=A-10-1-1322&slc_lang=en&sid=1 L.
