[Value of ultrasonography in the diagnosis and differential diagnosis of testicular tumor].

Objective: To evaluate ultrasonography in the diagnosis and differential diagnosis of testicular tumor.
Methods: Ultrasound findings and post-operation pathological results were retrospectively studied in 172 men with testicular mass 1998 to 2005.
Results: Of the total number, 50 cases were testicular hematoma, 13 testicular cyst, 26 testicular inflammatory node, 25 testicular tuberculosis and 58 testicular tumor. Among 59 testicular tumor cases, 50 were germ cell tumor (including 41 cases of seminoma and 9 cases of nonseminoma germ cell tumor), 6 were non-germ cell tumor and 3 were secondary tumor. The sonographic features of typical seminoma, teratomas, epidemic cyst, interstitial cell tumor and malignant lymphoma were obvious.
Conclusion: Ultrasonography, contributive to the preliminary diagnosis and differential diagnosis of testicular tumor and capable of evidence for further treatment, can be the first choice in medical imaging for the diagnosis of testicular tumors.
