A 60-year-old man visited our hospital to treat a large cystic mass in the pelvis which had been found by abdominal ultrasonography in December 201X. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a multilocular cyst with a maximum diameter of about 10 cm. CT-guided drainage and sclerotherapy with minocycline reduced the size of tumor by 40%, but symptoms such as difficulty of defecation and urinary frequency appeared a year and a half later due to re-enlargement of the cysts. Laparoscopic resection of the multilocular cysts was performed, and all cysts were removed almost completely using transrectal ultrasonography. The multilocular cyst was positive for NKX3.1 by immunohistochemical staining, and was diagnosed as a giant multilocular prostatic cystadenoma. After surgery, the symptoms such as difficulty of defecation and urinary frequency were relieved promptly. One year after the surgery, the patient was free from recurrence of the disease.
一名60岁男性因治疗盆腔内一个巨大囊性肿物前来我院就诊，该肿物于201X年12月经腹部超声检查发现。计算机断层扫描（CT）和磁共振成像（MRI）显示为一个最大直径约10 cm的多房性囊肿。CT引导下囊肿穿刺引流并注入米诺环素硬化治疗使肿瘤体积缩小了40%，但由于囊肿再次增大，一年半后出现了排便困难和尿频等症状。遂行腹腔镜下多房性囊肿切除术，术中经直肠超声引导几乎完整切除了所有囊肿。免疫组化染色显示多房性囊肿NKX3.1呈阳性，诊断为巨大多房性前列腺囊腺瘤。术后排便困难和尿频等症状迅速缓解。术后一年，患者疾病无复发。
