ミノサイクリン注入療法を行ったミュラー管嚢胞の1例

Abstract

A 29-year-old male was admitted for the examination of left flank pain. Abdominal ultrasonography revealed a cystic mass beneath the urinary bladder. Computed tomographic scan, magnetic resonance imaging and transrectal ultrasonography showed that this cystic mass was located between the bladder and the prostate. DIP, urethrocystography and seminal vesiculography demonstrated no communication between this mass and the urinary and the seminal tract. From these findings it was diagnosed a mullerian duct cyst. We obtained 15 ml of clear yellowish fluid which contained no sperm by fine needle aspiration under ultrasound guidance and injected minocycline for sclerotherapy. Left flank pain had disappeared and repeated ultrasonography showed a small cystic lesion. However, the size of the cyst was unchanged for six months after discharge. Twenty-five mullerian duct cysts reported in the Japanese literature were reviewed.
