Although surgical treatment is recommended in most cases of Bochdalek hernias, our patient did not receive surgical treatment because of his advanced age and his limited respiratory functions.
Most Bochdalek hernias are sporadic, with only 2% being familial [9].
In adults, most Bochdalek hernias are usually asymptomatic, and thus the finding of the condition is incidental [15].
