A 22-year-old male patient had admitted with pelvic pain and he-matospermia. There was no pathology on physical examination and blood tests. Deformation ratio of sperms was 86% and motility dis-
order ratio was 72% on semen analysis. Computed tomography (CT) scan 
revealed the lesion as a mass with 26 hounsfield unit (HU) density. Separa-
tion of solid-cystic initially failed,where upon magnetic resonance imaging 
(MRI) was performed. CT and MR pyelography showed an absent left kidney 
(Figure 1) accompanying cystic lesion in the high internal density located to 
the left posterio-lateral of the bladder (Figure 2). MRI examination of the le-
sion revealed cystic dilatation of left seminal vesicle with hyperintense sig-
nal changes on both T1 and T2 weighted images indicating a high content of 
protein (Figure 3). Right seminal vesicle was normal. The patient underwent 
diagnostic cystoscopy and there was no left ureteral orifice. Seminal vesicle 
cyst was surgically removed.
Seminal vesicle cysts (SVC) are seen with a prevalence of less than 0.005%.
(1) Patients usually present with irritative or obstructive voiding symptoms.
(2) They are usually detected in patients between 18 and 41 years of age, the 
period of maximal sexual and reproductive activity.(3) In about two-thirds of 
the patients with SVC, ipsilateral renal agenesis was also found.(1)
