Esophageal atresia (EA) is a relatively rare congenital anomaly. Esophageal pouch (EP) is the only direct sign of EA on fetal MRI, but is not always seen. Distended hypopharynx (DHP) has been reported as a useful prenatal sign of EA, but as EP and DHP are both subjective assessments, the prenatal diagnosis of EA is challenging. The aim of this study was to evaluate whether quantitative measurement of distended pharynx is useful in the diagnosis of EA. Read More

Congenital high airway obstruction syndrome (CHAOS) is a rare life-threatening disease and prenatal diagnosis is essential. Some characteristic features seen on fetal MRI are well-known: primary lesion (upper airway obstruction) and secondary changes (dilated trachea, flattened/inverted diaphragm, enlarged and hyperintense lung). It is also reported that these secondary changes may be reduced if tracheoesophageal fistula (TEF) is present. The aim of this study is to evaluate the accuracy of fetal MRI in the prenatal diagnosis of CHAOS by comparing results with those of normal fetuses. Read More

Congenital diaphragmatic hernia (CDH) is the result of incomplete closure of the normal pleuroperitoneal canal. CDH is usually detected prenatally or present in the newborn period with severe respiratory distress. In contrast, delayed presentation of CDH (D-CDH), defined as CDH diagnosed at later than 30 days of age, is known as rare subset of CDH. The outcome of patients with D-CDH is generally favorable, but misdiagnosis can result in morbidity and mortality. This educational exhibit will demonstrate clinico-radiological characteristics of D-CDH. Read More
