Echinococcal cysts usually involve the liver; extrahepatic localization is reported in 11% of all cases of abdominal hydatid disease. We report a case of a prevesical hydatid cyst. A 53-year-old man was admitted with a large suprapubic mass. Ultrasonography and computed tomography revealed a cystic mass situated in front of the urinary bladder. There were no cysts in any other location. Serological tests were positive for Echinococcus. The patient was operated on and the cyst was completely excised. The pathologic examination confirmed the diagnosis of Echinococcosis. Isolated hydatid cyst situated in front of the urinary bladder has never been described in the literature. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions, before any procedure like puncture, biopsy or cystectomy, in order to avoid dissemination of the cystic contents or an anaphylactic shock.
棘球蚴囊肿通常累及肝脏；据报道，在所有腹部包虫病病例中，肝外定位占11%。我们报告一例膀胱前棘球蚴囊肿病例。一名53岁男性因耻骨上巨大肿块入院。超声检查和计算机断层扫描显示膀胱前方有一个囊性肿块。其他任何部位均无囊肿。血清学检查棘球蚴呈阳性。患者接受手术，囊肿被完全切除。病理检查证实为棘球蚴病。文献中从未描述过孤立的位于膀胱前方的包虫囊肿。在流行地区，对于腹盆腔肿块进行鉴别诊断时，在进行任何如穿刺、活检或囊肿切除术等操作之前，都应始终考虑包虫囊肿，以避免囊肿内容物播散或过敏性休克。
