title: Imaging sacral nerve root cysts.
abstract: Sacral nerve root cysts usually are an incidental finding but may be found in patients with a history of pain. On computed tomography they are demonstrated as a soft tissue mass, possibly with associated bony erosion. Demonstrating the fluid-filled nature of these masses is important in establishing the diagnosis. The imaging of these cysts in two patients, including magnetic resonance, is described.
