Impalpable Testicular Seminoma Identified on Sonoelastography

AbstractThe role of sonoelastography in diagnosing cancerous masses has increased since the advent of elastography as an ultrasound modality. Its ability to display differences in the mechanical properties of cancerous masses compared to normal surrounding tissue has shown benefit in increasing the accuracy of diagnosing malignant breast and thyroid masses and has shown early potential in accomplishing better targeted prostate biopsies. To date, the literature is limited in the number of studies describing the use of sonoelastography for testicular masses. We describe a 34-year-old man who presented with an incidental finding of an impalpable hypoechoic testicular mass on grayscale ultrasound during an infertility work-up. Sonoelastography was performed displaying intermediate testicular elastic properties. Upon frozen section of the mass during surgical exploration, classic testicular seminoma was diagnosed and subsequent radical orchiectomy was performed. We would like to use this atypical presentation of testicular seminoma to review the potential role of elastography for diagnosing testicular cancer
