Sacral terminal filar cysts are a rare and distinctive type of sacral canal cyst, which are anatomically characterized by the presence of filum terminale within the cyst rather than nerve roots. Given their rarity and therapeutic challenges, the presentation of this case report aims to share a novel and effective treatment approach, providing valuable reference for clinicians.
A 39-year-old Chinese woman patient presented to our hospital with symptoms including lumbosacral pain, anal distension, increased frequency of urination, and incomplete urination. Magnetic resonance imaging scans revealed a sacral canal cyst compressing the adjacent sacral nerve roots. We performed minimally invasive surgery, guided by magnetic resonance imaging and computed tomography scans, to precisely remove the cyst. Six months postoperatively, a follow-up visit revealed normalized bowel and bladder functions, indicating a successful outcome.
The present study proposes an effective treatment strategy for sacral terminal filar cysts. Initially, magnetic resonance imaging scan results were employed to ascertain the location of the leak and to identify the corresponding cross-section of the leak in the computed tomography scan results. Subsequently, three-dimensional reconstruction of the computed tomography scan results was conducted to determine the extent of a visualized surgical incision. Ultimately, minimally invasive surgical treatment was performed.
骶尾部终丝囊肿是一种罕见且独特的骶管囊肿类型，其解剖学特征是囊肿内存在终丝而非神经根。鉴于其罕见性和治疗挑战，本病例报告的呈现旨在分享一种新颖且有效的治疗方法，为临床医生提供有价值的参考。
一名39岁的中国女性患者因腰骶部疼痛、肛门坠胀、尿频及排尿不尽等症状前来我院就诊。磁共振成像扫描显示一个骶管囊肿压迫相邻的骶神经根。我们在磁共振成像和计算机断层扫描的引导下进行了微创手术，精确切除囊肿。术后6个月的随访显示肠道和膀胱功能恢复正常，表明治疗成功。
本研究提出了一种针对骶尾部终丝囊肿的有效治疗策略。首先，利用磁共振成像扫描结果确定漏口位置，并在计算机断层扫描结果中识别漏口的相应横截面。随后，对计算机断层扫描结果进行三维重建，以确定可视化手术切口的范围。最终，实施了微创手术治疗。
