We report the case of a young girl with recurrent bladder dysfunction. Magnetic resonance imaging performed for evaluation of initial urologic symptoms revealed a low-lying conus medullaris. She underwent an L5 laminectomy and cord untethering by sectioning of the filum terminale. After initial improvement of bladder function, her symptoms returned 4 years later. Repeat magnetic resonance imaging demonstrated a new intradural lesion at L2. At surgery she was found to have an untethered, thickened, coiled filum terminale at L2.
我们报告了一例患有复发性膀胱功能障碍的年轻女孩的病例。为评估初始泌尿系统症状而进行的磁共振成像显示圆锥马尾低位。她接受了L5椎板切除术，并通过切断终丝进行脊髓松解。膀胱功能最初改善后，4年后症状复发。重复磁共振成像显示L2水平有一个新的硬膜内病变。手术时发现她在L2水平有一根未受牵拉、增厚且盘绕的终丝。
