Late-presenting congenital diaphragmatic hernia

Bochdalek hernia is a congenital defect of the posterolateral region of the diaphragm, usually on the left side.

The late onset is not frequent; it is intended to present a case of intestinal occlusion by late-presenting congenital diaphragmatic hernia (CDH), which was previously interpreted as a left pneumonia complicated with pleural reaction. New aspects were addressed when reviewing the medical literature on this topic. This case report is aimed at encouraging medical assessment towards this entity of rare onset
