Lymphangiography in patients with malignancy in a non-descended testicle

Lymphangiography was performed on 23 patients with malignancy in non-descended testicles, 14 of whom had seminomatous and 9 non-seminomatous tumors. Lymph node metastases were shown by lymphangiography in 8 patients: 3 in lumbar nodes, 1 in iliac nodes alone and 4 in lumbar and iliac lymph nodes. Microscopic metastases were shown in lumbar nodes at retroperitoneal lymph node dissection in 2 patients when the lymphangiograms were negative. Iliac lymph node metastases are rare in testicular tumors but may be seen in tumors of non-descended testicles, alone or in combination with lumbar metastatic disease. This information is extremely important for the radiologist as well as the clinician in the management of patients.
