Focal testicular lesion after sperm extraction or aspiration: Sonographic appearance simulating testicular tumor

OBJECTIVE. We describe the sonographic features of focal intratesticular le sions seen in men who underwent sperm retrieval procedures. CONCLUSION. Although many urologists believe that solid intratesticular mas ses are malignant until proven otherwise, a growing number of benign focal testicular lesions have been described. Awareness of the cause and sonograp hic appearance of focal abnormalities in men who have undergone testicular aspiration or extraction should help radiologists suggest the correct diagn osis and advise a conservative approach on the basis of close surveillance by serial physical, laboratory, and imaging studies.
