“…PSA value may or may not be elevated [ 1 ]. CT and in particular MRI can provide information on a large cystic process originating or not from the prostate (the origin is rarely determined by the imaging) [ 1 , 3–6 ]. In the CT scan, the lesion frequently present as a giant multiloculated mass composed of variable-sized cysts, with some septations enhancing after contrast administration.…”

“…In some cases, solid enhancing areas can be found within the lesion posing some diagnostic difficulties [ 1–4 ]. However, the most distinguish feature is that it present as well-defined non-infiltrative masses of indolent growth [ 3–5 ]. In fact, in the presented case, the lesion had sharp marinated borders, appearing to push the adjacent structures away and not invading into them.…”

“…Multilocular cystadenomas of the lower genitourinary tract are benign lesions [ 1–6 ] that originate from the prostate, less frequently from the seminal vesicles or cowper’s glands. Typically, it presents as multilocular cysts that varies in size from one patient to another and located most commonly between the rectum and the bladder [ 3 ]. Their presence manifests as obstructive or/and irritative LUTS or transit disorders [ 1–3 ].…”

Multilocular cystadenoma are benign lesions located most commonly between the rectum and the bladder. Their presence manifests as obstructive or/and irritative lower urinary tract symptoms or transit disorders. Computed tomography scan and magnetic resonance imaging may help to establish the diagnosis. Surgery is the established treatment standard, with a high risk of recurrence in case of incomplete excision of the lesions. Here we report a case of 59-year-old man presenting with an acute urinary retention due to a giant multilocular prostatic cystadenoma treated by complete excision. The diagnosis has never been suspected before surgery and has been confirmed histologically after complete excision.

“…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.…”

Rationale: Giant multilocular prostatic cystadenoma (GMPC) is a rare type of prostatic epithelial neoplasm. Thus, the imaging features of this condition are not well known. We report the imaging and clinical manifestations of a case of GMPC. Patient concerns: The case reported here relates to a 71-year-old man who complained of urination frequency and excessive urination at night. He underwent computed tomography (CT) and magnetic resonance imaging (MRI) examination before surgery, both tests revealed a mass body in the prostate. Diagnosis: Ultrasound-guided fine needle aspiration was performed and a diagnosis of GMPC was made by histological examination. Interventions: The patient received radical pelvic tumor resection successfully. Outcomes: Two months after surgery, the follow-up CT and magnetic MRI re-examination found no signs of recurrence. Lessons: GMPC is a rare prostatic neoplasm with atypical clinical symptoms. MRI provides valuable information about GMPC. In case of a giant multilocular prostatic mass with well-defined boundary and abundant vascularity, benign feature on diffusion-weighted imaging, GMPC should be considered.

“…Most patients present with voiding and storage urinary symptoms mimicking benign prostate hyperplasia [2,3]. A few of the patients present with haematuria [4] abdominal distention, abdominal mass [5,6] constipation [6] or infertility [7,8]. Over the years prostate cyst adenoma has been wrongly diagnosed, as in-depth literatures do not exist pertaining to this pathology and most definite diagnosis are done only after surgical resection.…”

A retrospective review of radiology registry identified 3 cases of diagnosed giant multilocular cystadenoma of prostate. The first case illustrates a 59-year-old man with worsening voiding and storage symptoms of 2 months duration. The prostate was enlarged with the right lobe being bigger than the left node and his PSA was 9.3 ug/l. MRI showed large Multi cystic mass from the prostate and TRUS biopsy revealed adenocarcinoma prostate. Neoadjuvant LHRH agonist shrunk the mass before radiotherapy. He has no urinary symptoms and PSA consistently less than 0.1. Repeat MRI showed highly shrunken mass. In the second case, we present a 79-year-old patient presenting with rising PSA despite being on finasteride. MRI diagnosed large cystic and solid mass arising from the prostate and extending to the abdomen. Tran's rectal ultrasound guided biopsy plus aspiration of the fluid from the multiloculated cyst revealed benign cystic adenoma with no evidence of any malignancy. Repeat MRI after 6 months of LHRH agonist showed multiloculated cyst adenoma of the prostate appears stable with no significant reduction in size and his PSA remains high. The third case is an 83-year-old presenting with LUTS, haematuria and rising PSA. He has a past medical history of low grade prostate cancer (diagnosed at TURP). MRI scan showed an enlarged echogenic prostate. TRUS biopsy of the mass identified complex proliferation of atypical glandular epithelium in a rather villous adenomatous pattern. Neoadjuvant LHRH agonist showed reduction in lower urinary symptoms. Keywords: Multilocular cystadenoma; Luteinising hormone releasing hormone; Cystic prostate cancer Case Reports Case 1A 59-year-old Caucasian man presented with both worsening urinary voiding and storage symptoms of 2 months duration. In addition, he complained of dysuria but he denied fever, chills, rigors or penile discharges. He has background history of hypertension and impaired glucose tolerance. He is a non-smoker and moderately consumes alcohol. On examination, his external genitalia were normal. The prostate was enlarged and non-tender. The right lobe of the prostate was bigger and irregular with palpable nodules. Urinalysis was negative and mid-stream urine grew no organism. His prostate specific antigen (PSA) was 9.3 ug/l. His flow rate was 15 ml/s and had a residual volume of 50 ml. In view of his high prostate specific antigen (PSA) and enlarged prostate, a Trans Rectal Ultrasound (TRUS) guided biopsy was done and revealed a focus of 3+4 (mostly 3) adenocarcinoma prostate. Magnetic Resonance Imaging (MRI) requested for staging showed a large multi-cystic mass lesion arising from lateral aspect of base of prostate, displacing bladder base superiorly and extending down right side of prostate to para-urethral tissues in the region of membranous urethra. Bone scan was negative. At urology, multidisciplinary team (MDT) an option of Luteinizing Hormone-Releasing Hormone (LHRH) was started with the aim of shrinking the mass to make it operable or to have radiotherapy. Repe...
