Summary
This case report details an infant with severe right diaphragm eventration and pulmonary hypoplasia, mimicking congenital diaphragmatic hernia. Surgical repair failed due to liver attachments and unclear defect, highlighting diagnostic challenges in rare diaphragmatic anomalies.
Area of Science:
- Pediatric Surgery
- Neonatal Medicine
- Thoracic Surgery
Background:
- Congenital diaphragmatic hernia (CDH) is a severe birth defect impacting lung development.
- Persistent pulmonary hypertension (PPH) is a critical complication in neonates with CDH.
- Diaphragmatic eventration, though less common than CDH, presents similar neonatal respiratory challenges.
Observation:
- An infant presented with severe right-sided diaphragmatic eventration and pulmonary hypoplasia.
- The infant's condition mimicked congenital diaphragmatic hernia with persistent pulmonary hypertension.
- Surgical intervention was attempted on extracorporeal life support.
Findings:
- Surgical correction was unsuccessful due to extensive liver adhesions preventing abdominal reduction.
- The precise nature of the diaphragmatic defect was indistinguishable from complete agenesis of the right hemidiaphragm.
- Autopsy revealed a rudimentary pulmonary remnant and a separating fibrous membrane between the lung and liver.
Implications:
- This case underscores the diagnostic and surgical complexities of severe diaphragmatic anomalies.
- Accurate differentiation between eventration and agenesis is crucial for surgical planning.
- Understanding anatomical variations is vital for managing neonates with congenital diaphragmatic abnormalities.
