A patient was referred at 21 weeks' gestation for unexplained fetal lung hyperechogenicity and ascites. Amniocentesis was normal. Fetal lung biopsy was consistent with the clinical diagnosis of cystic adenomatoid malformation of the lungs. However, autopsy of the stillborn infant demonstrated a cartilaginous bar, causing total laryngeal obstruction. The distinctive ultrasonographic appearance is presented.
