An intrathoracic homogeneous hyperechogenic mass diagnosed in the second trimester of pregnancy represents a challenge to the sonographer. A disappearance of such a finding is an enigma. We have recently encountered such a case in which a mucous plug obstructing a main bronchus was the causative factor. To the best of our knowledge, this is the first report of such an etiology in cases of vanishing fetal intrathoracic masses diagnosed by ultrasonography.
妊娠中期诊断出的胸腔内均匀高回声团块对超声检查医师来说是一项挑战。这样的检查结果消失是个谜。我们最近遇到了这样一个病例，其中阻塞主支气管的黏液栓是致病因素。据我们所知，这是超声诊断的胎儿胸腔内肿块消失病例中关于这种病因的首次报告。
