Evaluation of computed tomography in the management of testicular teratoma.

An analysis has been made of data obtained by computed tomography (CT) scanning in 100 patients with testicular teratoma. The results have been compared with information obtained by conventional staging procedures and changes in patient management occurring as a direct result of CT have been noted. Although these tumours are rare, their pattern of metastasis to the retroperitoneum, mediastinum, lungs and liver is consistent. Thus the value of CT scanning can be tested in all of these sites in each patient and the indications for scanning clearly defined.
