Sonographic appearance of duodenal atresia in utero

Prenatal ultrasonic diagnosis of congenital duplication of the stomach.

“…In utero detection of duodenal atresia relies upon identification of "double bubble" sign of the fetal abdomen, indicative of bowel obstruction. 11 There is usuallv an associated polyhydramnios. A communicating gastric duplication in the left upper quadrant could conceivably mimic a "double bubble" sign, making it difficult to differentiate from duodenal atresia.…”

Sonography of combined esophageal and duodenal atresia.

“…The ability of ultrasonography to diagnose duodenal atresia in utero has been documented. 1 appearance. McCook and Felman 4 and Hayden 5 have documented this finding in three other infants with combined esophageal atresia and duodenal atresia 4 but their reports are the only prior descriptions of this appearance.…”

Realtime Sonographic Diagnosis of Fetal Dysplastic Kidney

“…T h e presence of multiple sonolucent (echo-free) areas to the side of the fetal spine should strongly suggest a multicystic kidney. The differential diagnosis includes duodenal atresia, which presents the characteristic "double bubble" sign (8). It is further distinguished by the different location of the sonolucent areas in relation to the fetal spine and by the presence of polyhydramnios, whereas renal malformations are characteristically associated with oligohydramnios.…”

“…With the advent of gray scale sonography and higher resolution transducers, details of fetal structures have been visualized with relative ease. The prenatal diagnosis of some physical fetal anomalies has become feasible (5,8,10).…”
