Bronchopulmonary sequestration with morbid neonatal pleural effusion despite successful antenatal treatment

Abstract

Introduction: Bronchopulmonary sequestration (BPS) may cause prenatal pleural effusion (PE) or even hydrops. This case describes a fetus presenting with severe PE, which prenatally waned completely under steroid treatment, yet surprisingly reappeared rapidly after birth, requiring early surgical intervention. Case description: A male fetus was diagnosed with left BPS and severe PE. After three courses of prenatal steroid therapy for each recurrence of PE from 27 weeks of gestation, we observed a complete regression of PE prenatally. Yet, PE recurred 18 h after birth and persisted after repeated drainages and steroid therapy. Early total resection of the extralobar BPS was performed and led to complete recovery without recurrence of PE. Conclusion: This report underlines that in cases of BPS presenting with prenatal PE needing fetal intervention, even if full regression of PE is observed before birth, there might be a need for surgical excision during the neonatal period.
