Computed tomography and lymphography of the retroperitoneal space in testicular tumors. A comparison

The value of CT and lymphography of the retroperitoneum was compared in 31 patients with testicular tumors. In no patient with normal or equivocal lymphography was more information gained by CT. In abnormal cases, the presence of metastatic deposits was well detected at both examinations, but CT proved more useful in defining the exact extent of the tumor and facilitated the proper arrangement of the irradiation fields. A strategy in the sequence of investigation in testicular tumors is suggested, aiming to save CT time when CT information is not likely to be of significance for treatment planning.
