Concerning one case of cyst developing from embryological remnants in the retro-rectal space, the characteristics of these rare tumors are reviewed. The congenital cysts group is formed by teratomas and developmental cysts. Often they are uncovered when they become septic or when they compress adjoining organs. Computed tomography scan has proved valuable in the diagnosis of these lesions. But the precise diagnosis of a congenital cyst can only be made by pathological examination of the specimen after surgical removal. The possibility of malignant degeneration implies the systematic extirpation of any known pre-sacral cyst or tumor. Kraske's trans-sacral approach gives good access to the retro-rectal space. Sometimes, pelvic spread of these lesions requires the use of the abdominal approach. The prognosis for benign tumors is good, but it is poor for malignant tumors.
关于1例源于直肠后间隙胚胎残余组织的囊肿病例，对这些罕见肿瘤的特征进行了综述。先天性囊肿组由畸胎瘤和发育性囊肿组成。它们常在发生感染或压迫邻近器官时被发现。计算机断层扫描已被证明对这些病变的诊断有价值。但先天性囊肿的准确诊断只能通过手术切除标本的病理检查来确定。恶性变的可能性意味着要对任何已知的骶前囊肿或肿瘤进行系统性切除。克拉斯克经骶骨入路能很好地进入直肠后间隙。有时，这些病变的盆腔扩散需要采用腹部入路。良性肿瘤的预后良好，但恶性肿瘤的预后较差。
