IS Case 578: Left seminal vesicle cysts with left renal agenesis
Imaging Sciences URMC 2010
Publication Date: 2011-11-17
History
Patient is an 18-year-old male presenting to the emergency department after motor vehicle collision.
Findings
Several left seminal vesicle cysts versus dilated left seminal vesicle. Left renal agenesis.
Diagnosis
Left seminal vesicle cysts with left renal agenesis
Discussion
Congenital seminal vesicle cysts become symptomatic in young adulthood. Atresia of the ejaculatory ducts causes accumulation of secretions in the gland, distention, and cyst formation. Cysts are usually unilateral. Acquired cysts are seen with chronic prostatitis or with prostate surgery.
Congenital seminal vesicle cysts are associated with ipsilateral renal agenesis. Maldevelopment of the distal mesonephric duct leads to absence of the ureteral bud, and therefore ipsilateral renal agenesis and atresia of the ejaculatory duct with subsequent obstruction of seminal vesicles and cyst formation.
