Posterolateral Bochdalek diaphragmatic hernia in adults.

Bochdalek hernias (BHs) are produced in the posterolateral area of the diaphragm. They are generally congenital, appearing in childhood, but are also detected in asymptomatic adult patients seeking medical attention for other reasons. Computed tomography (CT) or magnetic resonance imaging (MRI) is used for the correct diagnosis of the hernia type and for its localization, facilitating its management and the choice of treatment.
