Computed Tomography and Conventional Radiography in Intrathoracic Metastases from Non-Seminomatous Testicular Tumor

Abstract

Conventional chest radiographs and CT scans were studied retrospectively in 283 patients with untreated non-seminomatous testicular tumor. Intrathoracic metastases were found in 47 patients, and CT was the only positive examination in 20 of them. Lung metastases were seen in 39 patients and mediastinal lymph nodes were involved in 13. The additional yield of CT in detecting only at CT in 9 out of 13 cases as compared with 14 out of 39 for the lung parenchyma). Posterior mediastinal and retrocrural lymph nodes were most often enlarged, and involvement of these was most difficult to detect at conventional radiography.
