title: [Efficacy of x-ray computed tomography in the diagnosis of tumors of the mediastinum. 103 cases].
abstract: A prospective study was carried out in 103 patients with mediastinal tumors to determine diagnostic value of CT imaging. A precise diagnosis was obtained in 80% of cases, the detection sensitivity being 100%, 98% and 71% respectively for fatty tumors (20 cases), solid tumors (59 cases) and cystic tumors (24 cases). The weak sensitivity of detection of cystic tumors was due to the spontaneously elevated density of mediastinal cystic tumors and the fact that 2 patients in this series with cystic lesions presented enhanced images with contrast. Sensitivity of detection of a malignant tumor was only 59%, due mainly for thymic tumors to extracapsular microscopic extensions undetected by CT scanning, which should however be included in exploratory techniques for mediastinal tumors.
