[Positional hypoxaemia complicating a Bochdalek hernia in an adult]

Bochdalek hernias are the result of a congenital defect of the postero-lateral part of the diaphragm, usually discovered in the neonatal period. The diagnosis is rare in adult life and usually follows an acute gastro-intestinal complication. We report the case of a 63 year old man presenting with positional hypoxaemia that could have been related to a left sided Bochdalek hernia.
