A case of bilateral obturator hernias; feasibility of combination study of computed tomography and ultrasonography to make diagnostic and therapeutic strategies.

Bilateral obturator hernias were diagnosed by computed tomography in a 77-year-old female. Ultrasonography was also performed and ultrasonographical difference was observed between right and left. This contributed the preoperative diagnosis of unilateral incarceration. Combination study with computed tomography and ultrasonography is thought to be feasible to make diagnostic and therapeutic strategies of obturator hernia.
