Computertomographischer Nachweis von Lymphknotenmetastasen bei malignen Hodentumoren

Abstract

Lymphography and computer tomography was performed on 64 patients with malignant testicular tumours in order to demonstrate lymph node metastases. In 60 patients it was possible to confirm the findings by surgery. In 43 patients there was agreement between the findings of the computer tomogram and the lymphogram. In 39 of these patients lymph node metastases had been demonstrated, in three there was a false negative and in one a false positive. Amongst the patients in whom there was a descrepancy between the two types of examination, the CT findings were confirmed histologically in twelve, and the lymphographic findings in nine. In 12.5% CT added significant additional information. Accuracy of lymphography was 73% and of computer tomography 80%. Specificity for each examination was 79%.

Therapy in Stage I Non-Seminomatous Testicular Tumor

“…Statements as to the percentage of false-negative results of computed tomography differ widely. Williams et al [67] report a rate of 7% while other authors find it to be up to 44% [9,10,28,41], Similar discrepancies exist regarding the combination of computed tomography and lymphography [10,28]. For a discussion of strengths and weaknesses of imaging tech niques see Husband [20].…”

Influence of Different Criteria for Abnormal Lymph Node Size on Reliability of Computed Tomography in Patients with Non-Seminomatous Testicular Tumor

“…This region usually contains enough fat to allow demonstration of lymph nodes with computed tomography (CT). Metastases from testicular tumors often produce bulky lymphadenopathy and this is particularly well demonstrated with CT (1,2,5,8,9,12,14,16,23).…”

Advances in Diagnostic Urology

“…It is also possible to evaluate the abdominal parenchymal organs for metastatic spread in the same examination (Lackner et al 1979). It is also possible to evaluate the abdominal parenchymal organs for metastatic spread in the same examination (Lackner et al 1979).…”
