Testicular sonography: Is an echogenic ring a sign of a benign lesion?

The differentiation of benign from malignant testicular lesions is important to avoid unnecessary surgical intervention but is often difficult, particularly in the case of focal hypoechoic lesions. We present the description of 3 cases of an echogenic ring that appeared around a hypoechoic testicular mass on sonograms. The ring proved to be a fibrous capsule around a benign lesion. If these observations are confirmed in larger series, the sonographic pattern described here may help reduce the number of orchiectomies performed for benign lesions.
