PURPOSE: To determine the ultrasonographic (US) abnormalities that may be encountered after testicular biopsy. MATERIALS AND METHODS: Testicular US studies in 33 patients (64 testes) who had undergone unilateral or bilateral testicular biopsy were retrospectively reviewed for evidence of postbiopsy changes. Biopsy had been performed in 55 testes. RESULTS: US abnormalities were found in 49 (89%) of 55 testes. These abnormalities included focal, hypoechoic, round lesions in five (9%) testes; focal hypoechoic lesions with linear margins in 27 (49%); ill-defined, localized, hypoechoic areas in four (7%); peritesticular echogenic foci in 40 (73%); linear hypoechoic striations in five (9%); and focal contour defects in three (5%). CONCLUSION: A range of US findings are encountered after testicular biopsy. The US appearance of a round hypoechoic lesion seen after biopsy can overlap with that of testicular malignancy. Other findings, such as hypoechoic lesion with linear margins, peritesticular echogenic foci, linear hypoechoic striations, and testicular contour defect, can be regarded as the benign sequelae of biopsy. In a patient with a focal, nonpalpable, hypoechoic, intratesticular lesion, a history of testicular biopsy should remind the radiologist of the increased likelihood of a benign change after biopsy, in which case follow-up US may be performed.
