Abstract

We report 2 cases of metastatic seminoma to emphasize the use of computed tomography in defining accurately the extent and volume of tumor before treatment. Computed tomography permits more direct visualization of the retroperitoneum, mesenteric and abdominal lymph nodes, and extra nodal extension of the tumor to other organ systems. Additionally, characteristic tissue densities are displayed (that is cyst and hemorrhage), which may serve as an index to the dynamics of tumor growth and change. Lymphography and venacavography are invasive studies and both share inherent limitations in imaging for seminoma. Cross-sectional imaging is more precise in describing treatment fields for radiation therapy. Results of treatment are monitored more confidently with computed tomography.
