Tailgut cysts are rare developmental cysts arising from remnants of the embryological postnatal gut. Despite being frequently located in the presacral space, isolated cases of aberrant locations have been reported, including, perirenal, perianal, and subcutaneous sites, with only two cases of subdural tailgut cysts reported to date. The clinical course is often marked by linear growth, causing compression of the adjacent structures, however malignant transformation with carcinomatous features has been previously described. Hereby the authors describe a case of an intradural extramedullary tailgut cyst in a 33-year-old man presenting with progressive low back pain and signs of autonomic dysfunction, including urinary retention and bowel incontinence. Whole-spine MRI revealed an intrathecal cystic lesion located at L2-L3 level exhibiting hyperintensity on T2-weighted images not enhancing when contrast was administered. Laminectomy followed by tumor excision was performed and pathological analysis confirmed the diagnosis of tailgut cyst.
尾肠囊肿是一种罕见的发育性囊肿，由胚胎期产后肠道的残余组织形成。尽管尾肠囊肿常位于骶前间隙，但也有孤立的异常位置的病例报道，包括肾周、肛周和皮下部位，迄今为止仅报道了两例硬脑膜下尾肠囊肿。其临床病程通常以线性生长为特征，导致相邻结构受压，不过此前已有恶变呈癌性特征的描述。在此，作者描述了一例33岁男性的硬脊膜内髓外尾肠囊肿病例，该患者表现为进行性腰痛和自主神经功能障碍体征，包括尿潴留和大便失禁。全脊柱磁共振成像显示位于L2-L3水平的鞘内囊性病变，在T2加权图像上呈高信号，注射造影剂后无强化。行椎板切除术并切除肿瘤，病理分析证实为尾肠囊肿。
