Congenital malformation of the diaphragm and left colon: Strangulated Bochdalek hernia in an adult

An unusual adult case of non‐traumatic diaphragmatic hernia through the foramen of Bochdalek is reported. Congenital abnormality of the diaphragm remained undetected until the emergency presentation in the sixth decade of life. It was associated with absence of the phrenicocolic ligament and extreme mobility of the left colon, which allowed its herniation into the thorax. The association of these embryological abnormalities of the diaphragm and the hindgut has not been previously described.
