title: Superior vena caval obstruction: detection using CT.
abstract: A review of 210 chest computed tomographic (CT) examinations demonstrating upper chest masses revealed 16 cases of superior vena caval obstruction (SVCO); 11 of these were clinically occult. Two of the occult cases subsequently became clinically evident. Contrast-enhanced chest CT permits the diagnosis of clinically occult SVCO and should be considered in patients with upper chest masses, even in the absence of any physical signs of SVCO.
