Background:
Elastography of the testis can be used as a part of multiparametric examination of the scrotum.
Purpose:
To determine the testicular stiffness using acoustic radiation force impulse imaging (ARFI) technique in men with testicular microlithiasis (TML).
Material And Methods:
In 2013, 12 patients with diagnosed testicular microlithiasis in 2008 (mean age, 51 years; age range, 25-76 years) underwent a 5-year follow-up B-mode ultrasonography with three ARFI elastography measurements of each testis. We used a Siemens Acuson S3000 machine.
Results:
No malignancy was found at the 5-year follow-up B-mode and elastography in 2013. However, we found an increase in TML; in the previous ultrasonography in 2008, eight men had bilateral TML, whereas in 2013, 10 men were diagnosed with bilateral TML. The mean elasticity of testicles with TML was 0.82 m/s (interquartile range [IQR], 0.72-0.88 m/s; range, 65-1.08 m/s).
Conclusion:
Elastography velocity of testis with TML seems to be in the same velocity range as in men with normal testis tissue.
