| Popis: | The purpose of this study is to determine the effectiveness of contrast-enhanced ultrasound in evaluating incidental focal testicular lesions in epididymitis.Intratesticular lesions ipsilateral to epididymitis were subject to B-mode color Doppler ultrasound and contrast-enhanced ultrasound, with their appearances reviewed in consensus. Final interpretation was by histologic analysis or follow-up ultrasound.Over 28 months, 16 focal testicular lesions (median lesion size, 24 mm; range, 14-48 mm) in 14 patients (median age, 49 years; range, 18-81 years) were examined. Lesions were oval (n = 14), wedge shaped (n = 1), or involved the entire testis (n = 1). Lesions were isoechoic (n = 1), hypoechoic (n = 4), or of mixed echogenicity (n = 11). Color Doppler ultrasound flow was not clearly depicted in 13 lesions but was present in three lesions, with contrast-enhanced ultrasound concordant with color Doppler ultrasound, showing unequivocal absence of vascularity and increased flow, respectively. In the avascular lesions, rim enhancement (n = 6), vascular projections (n = 4), and irregular (n = 10) and smooth (n = 2) borders were documented. The observers identified infarction (n = 9), abscess (n = 4), orchitis (n = 1), and tumor (n = 2). Histologic examination (seven lesions in five patients) confirmed infarction, abscess formation, and seminoma; follow-up ultrasound confirmed resolution for eight patients.Contrast-enhanced ultrasound is a useful adjuvant to color Doppler ultrasound examination of a focal lesion in the testis ipsilateral to epididymitis to improve the characterization of nonvascularized tissue. |
