摘　　要：Tailgut cyst is a rare congenital cystic lesion arising from the remnants of the embryonic postanal gut. It occurs exclusively within the retrorectal space and rarely in the perirenal area or in the subcutaneous tissue. A prerectal and retrovesical location of tailgut cyst is extremely rare. To the best of our knowledge, only three cases have been reported in the English literature. We experienced an unusual case of tailgut cyst developed in the prerectal and retrovesical space in a 14-year-old boy. Abdominal computed tomography demonstrated a prerectal cyst which was located at the anterolateral portion to the rectum. The cyst contained yellowish inspissated mucoid material. Microscopically, the cyst was lined by squamous, columnar, cuboidal and transitional epithelia and the wall was fibrotic with dispersed smooth muscle cells. Although tailgut cyst arising in prerectal area is extremely rare, its possibility should be considered in differential diagnosis of a prerectal and retrovesical cystic mass.尾肠包囊是从胚胎的柱子的残余产生的稀罕先天的膀胱的损害肛门勇气。它专门在制动火箭以内发生直肠的空间并且很少在仙子肾的区域或在皮下组织。直肠前和制动火箭肛后肠包囊的膀胱的地点是极其稀罕的。就我们的知识而言，仅仅三个案例在英语文学被报导了。我们经历了在直肠前和制动火箭开发的肛后肠包囊的一个不平常的案例在一个 14 岁的男孩的膀胱的空间。腹的计算断层摄影术表明了在在前面偏一边的部分被定位到直肠的直肠前包囊。包囊包含了微黄色的使浓厚的类粘蛋白材料。用显微镜，包囊被有鳞、圆柱、立方形、过渡的上皮衬里，墙是有驱散的平滑肌房间的纤维变性。尽管肛后肠包囊在直肠前区域产生是极其稀罕的，它的可能性应该在直肠前和制动火箭的鉴别诊断被认为膀胱的膀胱的质量。
