COMPUTERIZED TOMOGRAPHIC APPEARANCE OF HERNIAS OF THE BLADDER

Herniation of the bladder is not uncommon and it can occur with any ty pe of hernia in the groin. Most bladder hernias are discovered unexpec tedly during herniorrhaphy, and serious complications can result from intraoperative injury to the bladder. The appearance of hernias on exc retory urography and cystography has been described extensively but ex perience with computerized tomography (CT) has been limited. We descri be the appearance of 8 bladder hernias on CT: 2 incisional, 2 femoral, 3 small direct inguinal, and 1 massive direct inguinal hernia with bl adder necrosis and perforation. Appearance on CT is characteristic, an d this modality may be useful for preoperative evaluation.
