A large acquired seminal vesicle cyst presenting with urinary symptoms: a case report

Seminal vesicle cysts are infrequent urogenital lesions, typically classified as congenital or acquired. Acquired cysts usually develop due to chronic obstruction, inflammation, or infection. This report describes the clinical course, evaluation, and surgical management of a large acquired seminal vesicle cyst in a 55‑year‑old man who presented with lower abdominal discomfort, urinary difficulty, and intermittent hematuria. Cross‑sectional imaging revealed a sizable cystic lesion arising from the left seminal vesicle, and definitive treatment was achieved through open surgical excision after failed laparoscopic dissection. The patient recovered well and remained symptom-free postoperatively.
