title: Potential for a normal fetal stomach to simulate the sonographic "double bubble" sign.
abstract: The ultrasonographic appearance of the normal fetal stomach may simulate duodenal atresia when the incisura angularis is prominent. Such an erroneous diagnosis can be avoided by noting the absence of polyhydramnios and by assessing the fetal stomach in planes which traverse its long axis with real-time scanning units.
