Congenital diaphragmatic hernia diagnosed prenatally by ultrasound.

Abstract

Seven infants born at our institution between July 1979 and June 1982 had congenital diaphragmatic hernia (CDH). Four cases of CDH were correctly identified by fetal ultrasonography. Diagnosis relied upon the demonstration of abdominal organs within the thorax. During this period, no false positive diagnoses of CDH were made. Significant associated sonographic features included polyhydramnios, mediastinal displacement, and distorted upper abdominal anatomy.

Antenatal diagnosis of a Morgagni hernia in the second trimester

“…5 Such a peritoneopericardial hernia probably occurs as a result of failure of the retrosternal portion of the septum transversum to close the communication between the pericardial and peritoneal cavities. 9 Septum transversum also contributes to the development of the diaphragm, falciform ligament, liver, and pericardium.…”

“…2,4 Herniation of the liver into the fluid-filled pericardial sac resulting in a thoracic mass is a particularly rare form of Morgagni hernia. 5 To the best of our knowledge, only 3 cases of this type of Morgagni hernia have been reported in the English literature as being diagnosed antenatally. [6][7][8] In all these cases, the diagnosis was established at 32 weeks' gestation or later.…”

Congenital Cystic Adenomatoid Malformation of the Lung: A Case Report and a Brief Review

“…10,16,17,18 Diaphragmatic hernia can be ruled out by demonstration of an intact diaphragm, and if doubt remains, by an amniogram. 6,19 Other conditions in the differential diagnosis include pulmonary sequestration, bronchogenic and enteric cysts, and mediastinal teratoma. [20][21][22] Symptomatic newborns with respiratory distress should have a chest x-ray study done as soon as possible.…”

Diagnosis of Congenital Diaphragmatic Hernia (CDH)

“…Right-sided defects tend to involve the liver and gallbladder,so they may be more difficult to diagnose due to similarities in echogenicity of fetal lung and liver (27). Sonographic findings commonly identified in conjunction with posterolateral diaphragmatic hernias include cystic or solid intrathoracic masses corresponding to abdominal organs, mediastinal shift, smaller than expected abdominal circumference, and, failure to identify a fluid filled stomach in the left upper quadrant (25,26,27). Polyhydramnios is frequent and pleural effusions or ascites are occasionally seen.…”
