Late-presenting congenital diaphragmatic hernia mimicking bronchiolitis.

We report a case of a late-presenting congenital diaphragmatic hernia (CDH) in an otherwise healthy infant initially presenting to the emergency department with wheezing and respiratory distress. Late-presenting CDH can manifest a vast array of clinical symptoms and therefore may frequently masquerade as other more common pediatric entities. Prompt and accurate diagnosis is essential in the management of late-presenting CDH; patients may be critically ill at presentation, and selection of appropriate therapeutic interventions may avoid potentially life-threatening complications. In this case report, we seek to inform emergency physicians about this rare, but serious, disorder.
