Giant multilocular prostatic cystadenoma, a diagnosis to consider in large pelvic male masses

Abstract

Giant multilocular prostatic cystadenomas are rare benign prostatic tumor, usually presenting as a large pelvic mass, compressing the adjacent organs but with no clear aggressive features, frequently causing obstructive voiding symptoms. Nowadays, imaging plays an important role on the adequate characterization of these lesions, not only on depicting their different internal components, but also the relationship with the adjacent structures, therefore providing the best preoperative surgical planning. Here we present a case of a 62-year-old patient with recurrent obstructive voiding symptoms due to a giant multilocular prostatic cystadenomas, with histologically correlation, posteriorly excised.

Giant multilocular prostatic cystadenoma in a young man: A case report from Jordan

“…Patients with GMPC could be falsely diagnosed to have giant benign prostatic hyperplasia (BPH), and this is due to the shared obstructive and irritative urinary symptoms between the two clinical entities. 1 , 2 , 3 , 5 Less common symptoms of GMPC include palpable abdominal mass, constipation, and obstructive azoospermia. 2 , 5 In our case, the patient has also suffered from constipation which was mostly attributed to the mass effect on the rectum caused by the prostatic lesion.…”

“…However, due to its location and the mass effect, typical symptoms for patients with this rare lesion are obstructive voiding or retention symptoms. 3 Additionally, the patients can suffer from constipation, accounting for the mass effect on the rectum in case of large lesions. Here, we present a case of a young man from Jordan who has been recently diagnosed to have GMPC.…”

CT and MRI findings of a stromal tumour of uncertain malignant potential of the prostate

“…Cystic epithelial tumours of the prostate show multilocular cyst macroscopically. There are several case reports of cystic epithelial tumours diagnosed as giant multilocular cystadenoma, including by ultrasound, CT, and MRI findings [2,3]. These tumours often present as a large multilocular cystic mass composed of variable-sized cysts, usually with some thin enhancing septations and an outer, thin, enhancing wall.…”

“…Nonneoplastic lesions include Müllerian duct cysts, prostatic utricle cysts, retention cysts, paramedian cysts, infectious cysts, and seminal vesicle cysts [1]. Although non-neoplastic cystic lesions are common, neoplastic cystic lesions arising from the prostate are rarely reported [2,3]. Recent studies have proposed that a spectrum of cystic epithelial tumours arise from the prostate glandular epithelium with multilocular cysts macroscopically and with malignant potential [4].…”

Imaging and clinical features of giant multilocular prostatic cystadenoma

“…However, CT alone is not effective in making an accurate diagnosis. Due to its excellent soft tissue resolution, MRI may provide more information [ 6 , 7 , 10 ] on the broader and compositions of the tumor. The surrounding tissue invaded or compressed by the tumor can be seen clearly in multiple MR sequences.…”
