目的：研究了51例椎管肿瘤并脊髓空洞症的MRI诊断和鉴别诊断。方法：全部病例均用SE序列进行矢。横断面成像。结果：椎管内肿瘤好发于颈胸髓，局部脊髓增粗，信号不均匀，瘤巢均有明显强化，有37.3％的脊髓内肿瘤发生囊变，囊壁水肿较明显。脊髓空洞位置远离肿瘤，范围明显较肿瘤为广，平均累及6.48个脊椎节段。偏心型和多腔空洞较多见（58％），少数可见肘脊液流空现象（CFVP），本文对脊髓空洞症的发病机理进行了探讨。结论：MRI是本病最有效的检查方法;增强扫描对于鉴别脊髓内空洞、肿瘤囊变与正常脊髓有十分重要的意义。
Objective: To study MRI diagnosis and differential diagnosis of 51 cases of spinal tumors with syringomyelia. Methods: All cases were vectorized with SE sequences. Cross-sectional imaging. Results: The tumors of the spinal canal occurred in the cervical and thoracic spinal cord. The local spinal cord was thick and the signal was not uniform. The tumor nests were obviously strengthened. There were 37.3% cystic lesions in the spinal cord tumor and obvious cyst wall edema. Syringomyelia away from the location of the tumor, the scope was significantly wider than the tumor, involving an average of 6.48 spine segments. Eccentric and multi-cavity voids are more common (58%), a few can see elbow spinal fluid empty phenomenon (CFVP), the paper discussed the pathogenesis of syringomyelia. Conclusion: MRI is the most effective method for the diagnosis of this disease. Enhanced scanning is very important for differentiating intramedullary cavity, cystic degeneration and normal spinal cord.
