Diagnosis of Diaphragmatic Hernia with Associated Congenital Lung Lesions: Contribution of Fetal MRI

Abstract

This report describes 2 cases of congenital diaphragmatic hernia with associated congenital lung lesion which were diagnosed antenatally using ultrasound (US) and magnetic resonance imaging (MRI). We describe the antenatal imaging findings and the short-term postnatal outcome. Association of these fetal pathologies is rare and a challenging diagnosis. MRI supplements US in the evaluation of the lung parenchyma and its volume, in particular in the setting of distortion of the normal intrathoracic anatomy.

Fetoscopic tracheal occlusion for treatment of non‐isolated congenital diaphragmatic hernia

“…The presence of a lung lesion may interfere with early embryonic diaphragmatic fusion potentially explaining the association of CPAM with CDH . Some have argued that an intrathoracic lung mass might be advantageous by preventing intrathoracic herniation of abdominal contents, while others believe it more likely that the two coexisting intrathoracic masses decrease the total functional lung volume, resulting in a poorer prognosis than with either lesions found in isolation . While it is generally believed that the CDH severity is the primary determinant of outcome when a CPAM is also present, this has not been systematically examined.…”

Malformaciones pulmonares congénitas

“…La ecografía prenatal evidenciar una área multiquística en el tórax. La resonancia magnética fetal (RMF) es útil en los casos en los que el diagnóstico no es claro (13). Se debe plantear el diagnóstico diferencial con hernia diafragmática.…”
