Clinics in diagnostic imaging (107).

Abstract

A 90-year-old woman was admitted for progressively increasing lower abdominal pain. There was no history of prior surgery, and physical examination was non-specific. The supine abdominal radiograph revealed an abnormal collection of air over the right obturator foramen. Computed tomography showed a right obturator hernia with incarcerated bowel in the hernial sac, and a right sciatic hernia containing the right ovary. The anatomy of obturator and inguinal hernias is reviewed, and the use of various imaging modalities in evaluation of abdominal hernias is discussed.
