Abstract
- Objectives: To analyze the sensitivity and specificity of high resolution ultrasound in testicular tumors.<br />Methods: The study comprised 18 histologically confirmed testicular tumors. Patient ages ranged from 19 to 79 years (mean 41). The ultrasound and the anatomopathological findings were compared.<br />Results: 12 of 18 were primary testicular tumors: 5 classical seminomas, 1 spermatocytic seminoma, 1 anaplastic seminoma, 3 embryonary carcinoma, 1 mixed teratoma and 1 immature teratoma. Ultrasound detected all tumors, accounting for a sensitivity of 100%. All tumors were hypoechoic. Substantial differences were observed between the classical seminomas and the other tumor types: the echo structure was homogeneous in 60% of the classical seminomas vs 50% for the other tumor types; 80% of the former and none of the other tumor types had well- or partially well-defined tumor margins; and finally, cystic or hyperechoic areas were not observed in the classical seminomas but in 30% of the other tumors.<br />Conclusion: High resolution ultrasound should be performed if testicular tumor is suspected. This technique will confirm or discard this condition and, furthermore, if the ultrasound findings show a solid, hypoechoic lesion, regardless of the degree of definition of the tumor margins, with no cystic or hyperechoic areas, a presumptive diagnosis of classical seminoma can be made.
