Bladder in Inguinal Hernia

This was an incidental finding in a male patient in his 50s. There is a large indirect inguinal hernia, and it contains not bowel, but bladder, as can be seen on this oblique coronal reformat of an abdominopelvic CT.
Between 1 and 3 percent of all inguinal hernias contain bladder. Sometimes a bladder hernia may involve nearly the entire bladder. It is important for the surgeon to be aware of this before surgical repair is attempted, as ligation of the bladder carries a risk of serious complications.
Most bladder hernias are asymptomatic, but they may be associated with dysuria or frequency.
