[CT-evaluation in patients with testicular tumors (author's transl)].

Fifty CT examinations of 31 patients with testicular tumours were evaluated. In 13 patients, the CT findings were compared with results of histological-surgical or autoptic findings. Comparative evaluation of CT, lymphography and other methods of diagnosis is demonstrated. The high incidence (80 %) of correct CT results is emphasised, in staging patients and in the work up of patients with long treatment time and history of tumor recurrence. The advantages of CT are: 1) possibility of exact localisation and determination of tumor-size, as well as discovery and assessment of their patho-anatomic relations to the adjacent organs, 2) utilisation of these data in the planning of radiotherapy, 3) the possibility to document exactly any treatment sucess (reduction of tumor size). In more than 30 % of the patients, CT scanning revealed, despite radiological preliminary examinations, clinically and radiologically unexpected pathologic findings, such as osseous metastases (17%), non functioning kidneys, metastases in the liver and pleura.
