Adenomyosis of the seminal vesicle with hematospermia

Abstract

62歳, 男性.血精液を主訴として来院.精嚢炎を疑い抗菌剤投与を行い軽快した。その後再発したため, 尿道膀胱鏡を行ったが異常を認めなかった.精嚢造影では右精嚢は描出されず, CTにて前立腺右背側に内容均一な腫瘤を認めた。経直腸超音波検査にて右精嚢の腫大を認め, 超音波ガイド下生検を行ったところ, 明らかな異常所見をえられなかった.診断目的で手術を行い前立腺および精嚢を摘出した.病理学的診断は精嚢腺筋症であった.

A 62-year-old man presented in 1987 with hematospermia. No abnormal findings were observed by cystourethroscopy. Ultrasound showed the enlargement of the right seminal vesicle. The right seminal vesicle could not be visualized by seminal vesiculography. Computed tomographic scan revealed a homogeneous mass at the right dorsolateral aspect of the prostate. Surgical exploration was performed. The prostate and bilateral seminal vesicle were resected. Pathological diagnosis was adenomyosis of the right seminal vesicle.
