BACKGROUND:

seminal vesicle cysts are rare entities. Their estimated incidence is 0.005% and they are more frequently diagnosed between the second and fourth decades of life. The majority of cases present as a single lesion, but multiple lesions have been reported. They are congenital or acquired, and the former is associated with mesophrenic duct (Wolffian duct) alterations. Two thirds of the cases include the presence of ipsilateral renal agenesis (Zinner syndrome). The acquired form is associated with obstructive, presumably infectious, causes.

CLINICAL CASE:

a 43-year-old man sought medical attention for lower urinary tract voiding symptoms, accompanied with hematospermia, rectal tenesmus, and pelvic pain.

DISCUSSION:

varying forms and degrees of clinical presentation have been observed in patients with seminal vesicle cysts. Some patients are asymptomatic, whereas others present with lower urinary tract symptoms, urinary infections, hematuria, hematospermia, and even infertility. Large cysts can be accompanied with gastrointestinal symptoms, such as constipation and rectal tenesmus. Because it is a rare condition, there is no consensus on the treatment and management of these patients. At present, treatment is reserved for symptomatic patients. Different authors propose the endoscopic approach as first-line treatment, considering vesiculoscopy as the criterion standard in seminal vesicle cyst management.
