Segmental hemorrhagic infarction of testis associated with epididymitis.

Testicular infarction is most commonly associated with acute testicular torsion. We present the sonographic findings in a case of segmental testicular infarction associated with epididymitis. The gray-scale abnormalities included a round, well-defined, hypoechoic intratesticular mass and heterogeneity and enlargement of the epididymis. Color Doppler sonography demonstrated only minimal blood flow in the intratesticular mass and increased flow in the epididymis. Recognition of acute testicular segmental infarction as a complication of epididymitis may prevent unnecessary orchiectomy.
