Background: seminal vesicle abscesses are usually misdiagnosed due to the rarity of this pathology and can be mistakenly diagnosed as an inguinal hernia or scrotal abscess even with the aid of computerized tomography of the abdomen and pelvis. We report a case where a pre-operative diagnosis was difficult owing to the atypical presentation with Fournier gangrene. Aim of the work: To the best of our knowledge, our case is the first to report a seminal vesicle abscess presenting as Fournier's gangrene. We believe it can add to the scarce literature and help increase the index of suspicion for such rare urological condition. Results: For our patient, the transurethral approach was successful without any complications and he was asymptomatic and able to void on the third day postoperative. Conclusion: the transurethral drainage is a good alternative to transrectal drainage with comparable hospitalization period and symptoms relief. Also, it ensures complete drainage of the abscess cavity.
