Müllerian duct cyst: Case report, embryology, pathogenesis and therapeutic options

We report the case of a 56-year-old male suffering from acute urine retention after a period of increasing dysuria. Physical examination, TRUS and CT showed the presence of a multilocular cystic mass in the space above the prostate and behind the bladder. Pathological findings following surgical exploration indicated a Müllerian duct cyst, few cases of which have been reported in literature. We performed surgery because malignancy was suspected and it was impossible to drain off all the cystic fluid due to the multilocular nature of the cyst. Moreover, cystic adenocarcinomas originating from Müllerian duct remnants have been reported. We agree with other authors that a percutaneous approach should be standard treatment in these cases, leaving open surgery for more complex cases.
