title: [Segmental infarction of testicle presenting as right acute scrotum: a case report].
abstract: We report a case of segmental infarction of a testicle seen in a 28-year-old man with right lower abdominal pain who visited our hospital. On physical examination, the right testicle was slightly elevated and Prehn's sign was positive. As torsion of the right spermatic cord was suspected, ultrasonography and color Doppler sonography were performed, revealing sufficient blood supply in the right spermatic cord and in the most part of the right testicle. However, a low echogenic area without blood flow was noted in the upper pole of testicle. Since CT and MRI findings couldn't rule out a testicular tumor, right high orchiectomy was performed. The specimen revealed a hemorrhagic area, histologically proved to be segmental hemorrhagic infarction of the testicle. Segmental infarction of a testicle is rare and our case is the 31st case in the world literature (the 7th case in Japan).
