[Seminal vesicle cysts and infertility in autosomal dominant polycystic kidney disease].

Autosomal dominant polycystic kidney disease (ADPKD) is a systemic hereditary disorder characterized by bilateral diffuse renal cysts. Extrarenal involvement is a well known manifestation of ADPKD. Cysts in the liver, pancreas, lung, spleen, oesophagus, ovary, testis, epididymis, prostate, thyroid, bladder, uterus, brain, paraespinal, and seminal vesicle have also been described. The occurrence of seminal vesicle cysts is often unrecognised. We report here a man with seminal vesicle cysts and azoospermia associated with ADPKD. Seminal vesicle cysts are not uncommon in ADPKD and in some cases it is associated with infertility. Ultrasound and computed tomography imaging were effective in documenting the underlying lesions non-invasively. Studies evaluating fertility in patients with seminal vesicle cysts and ADPKD are needed.
