We report a rare case of aneurysmal dilatation of filum terminale artery after resection of filum terminal myxopapillary ependymoma.
The authors report a rare aneurysmal dilatation of the filum terminale artery following removal of a filum terminal myxopapillary ependymoma in a 10-year-old male. The patient presented with 6-month history of increasing back pain without a focal neurological deficit. Magnetic resonance (MR) showed an intradural filum terminale lesion that was completely excised. Three months later, the MR again revealed a lesion involving the filum terminale. During the second surgery, however, an aneurysmal dilation of the filum artery was found, which was coagulated and resected. Following the secondary surgery, the patient's symptoms gradually resolved, and he remains intact.
Although rare, a true aneurysm after spinal surgery should be considered among the differential diagnostic consideration in the region of the filum terminale.
我们报告了一例在终丝黏液乳头型室管膜瘤切除术后终丝动脉动脉瘤样扩张的罕见病例。
作者报告了一名10岁男性在切除终丝黏液乳头型室管膜瘤后终丝动脉出现罕见的动脉瘤样扩张。该患者有6个月的背痛加重病史，无局灶性神经功能缺损。磁共振成像（MR）显示硬膜内终丝病变，该病变被完全切除。三个月后，MR再次显示涉及终丝的病变。然而，在第二次手术中，发现终丝动脉有动脉瘤样扩张，对其进行了凝固和切除。二次手术后，患者症状逐渐缓解，目前情况良好。
尽管罕见，但在终丝区域进行鉴别诊断时，应考虑脊柱手术后出现真性动脉瘤的情况。
