Seminal Vesicle Cyst with Ipsilateral Renal Agenesis

Abstract

Patients with seminal vesicle cysts associated with renal agenesis may present with symptoms of bladder irritation or obstruction and with an abdominal or pelvic mass revealed on physical examination. Differentiation of a seminal vesicle cyst from other pelvic cystic masses may be determined with a spectrum of imaging techniques including excretory urography, sonography, CT, and MR imaging.

“…[2] The maldevelopment of the distal mesonephric duct and faulty ureteral budding may lead to renal agenesis or dysplasia, and atresia of the ejaculatory duct may cause obstruction and cystic dilatation of the seminal vesicle. [3] SVCs measuring < 5 cm in diameter are usually asymptomatic. [3,4] Symptomatic SVCs usually occur in the second to fourth decades of life, as the result of accumulated seminal fluid in the seminal vesicle caused by a blocked ejaculatory duct.…”

“…[3] SVCs measuring < 5 cm in diameter are usually asymptomatic. [3,4] Symptomatic SVCs usually occur in the second to fourth decades of life, as the result of accumulated seminal fluid in the seminal vesicle caused by a blocked ejaculatory duct. [1,5] Symptoms generally develop because of irritation of the adjacent organs by the enlarged and inflamed cyst.…”

“…[2] Different types of imaging techniques, including excretory urography (EU), USG, computerized tomography (CT) and MRI can be utilized in a differential diagnosis of SVC from other cystic pelvic masses. [3] As initial diagnostic tools, SG or TRUSG can confirm the cystic content of the pelvic masses and determine the sizes and locations. [2,3] EU can exhibit ipsilateral renal agenesis.…”

“…[3] As initial diagnostic tools, SG or TRUSG can confirm the cystic content of the pelvic masses and determine the sizes and locations. [2,3] EU can exhibit ipsilateral renal agenesis. However, SVC may not be clearly visualized with this method.…”

“…However, SVC may show hyperintensity on both sequences because of proteinaceous material or hemorrhage. [3] MRI features, including multiplanar imaging capability, superior softtissue contrast, and lack of ionizing radiation, makes it a better tool to accurately define anatomic relationships when one is planning to excise a seminal vesicle cyst or if one is considering a difficult differential diagnosis. MRI may also reveal the opening of the associated ectopic ureter.…”
