Lee BH, Seo JW, Han YH, Kim YH, Cha SJ - Korean J Radiol (2007 May-Jun)

Bottom Line: Primary adenocarcinoma of the seminal vesicles is a rare neoplasm.Congenital seminal vesicle cysts are commonly associated with unilateral renal agenesis or dysgenesis.To the best of our knowledge, mucinous adenocarcinoma of the seminal vesicle cyst that's associated with an ectopic ureter opening into the seminal vesicle and ipsilateral renal agenesis has not been described in the radiological literature.

ABSTRACT
Primary adenocarcinoma of the seminal vesicles is a rare neoplasm. Congenital seminal vesicle cysts are commonly associated with unilateral renal agenesis or dysgenesis. To the best of our knowledge, mucinous adenocarcinoma of the seminal vesicle cyst that's associated with an ectopic ureter opening into the seminal vesicle and ipsilateral renal agenesis has not been described in the radiological literature. We report here on the radiological findings of a primary adenocarcinoma of a seminal vesicle cyst in this condition.

A 41-year-old man with adenocarcinoma of the seminal vesicle cyst associated with an ectopic ureter opening into the seminal vesicle and also ipsilateral renal agenesis.A. Transrectal ultrasonography shows a hyperechoic, intraluminal protruding papillary mass (white arrows) in the cystic change of the left seminal vesicle (black arrows).B. On the contrast-enhanced pelvic CT scan, the papillary solid mass (black arrows) is seen to originate from the wall of the left seminal vesicle cyst (white arrows), and this mass is mildly enhanced.C. A small, abnormal soft tissue density (white arrows) is noted in the aorta's left lateral aspect, suggesting an atrophic or dysgenetic left kidney on the contrast-enhanced abdominal CT at the level of the L4 vertebra.D. An axial T1-weighted MR image shows a large, dilated seminal vesicle (white arrows) with fluid content that has high signal intensity. The cyst contains a low signal intensity papillary mass (arrowheads). The urinary bladder (black arrows) is also noted.E, F. The T2-weighted coronal (E) and sagittal (F) MR images disclose a low signal intensity papillary mass (black arrows) in the left seminal vesicle cyst and a dilated left ectopic ureter (white arrows) draining into the left seminal vesicle.G. The gross specimen shows the internal surface of the seminal vesicle cyst with a residual papillary mass (arrows). The main mass is removed.H. A photomicrograph shows a papillary configuration (black arrows) covered with carcinoma cells without muscular invasion (white arrows) (Hematoxylin & Eosin staining, × 100).

Mentions: A 41-year-old man presented with terminal gross hematuria that was noted one month earlier. His past medical history was unremarkable except that he had suffered with prostatitis. The serum markers for prostate cancer, prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) were normal. Carcinoembryonic antigen (CEA) was also in the normal range. Transrectal ultrasonography showed a well-demarcated, pear-shaped cystic lesion that included an echogenic papillary solid mass in his left seminal vesicle (Fig. 1A). Contrast-enhanced pelvic CT showed that the papillary solid mass originated from the wall of the left seminal vesicle cyst and it was mildly enhanced (Fig. 1B). A dilated ectopic ureter opening into the dilated left seminal vesicle was also seen. There was no evidence of any other pelvic tumors. Contrast enhanced abdominal CT at the level of the L4 vertebra demonstrated a small abnormal soft tissue density in the aorta's left lateral aspect, suggesting a dysgenetic or atrophic kidney (Fig. 1C). The axial T1-weighted (TR/TE: 540/12 ms) MR image showed high signal-intensity fluid in the seminal vesicle cyst (Fig. 1D). The coronal T2-weighted (TR/TE: 5500/136 ms) MR image demonstrated an approximately 7.8 × 6 × 5.2 cm papillary mass in the left seminal vesicle cyst (Fig. 1E). The sagittal T2-weighted image showed a markedly dilated ectopic ureter draining into the cyst (Fig. 1E). The cystoscopic findings showed bulging of the left hemitrigone on the left side of the bladder. The left ureteral orifice was absent.

We report here on the radiological findings of a primary adenocarcinoma of a seminal vesicle cyst in this condition.
