摘要
目的研究椎管内肠源性囊肿的MRI表现。方法回顾分析20例经手术病理证实的肠源性囊肿的MRI表现及相关临床资料。结果19例位于脊髓腹侧的髓外硬膜下间隙,其中颈段椎管10例,颈胸段4例,胸段5例;胸段脊髓内1例。所有病变平扫表现为长或等T1、长T2信号,边界清楚,信号均匀。15例呈“脊髓嵌入征”。所有病变未见强化。4例合并其他脊椎畸形。结论根据病灶典型的形态及信号特点及好发部位,MRI能在术前正确地诊断肠源性囊肿。
Objective To study the MRI manifestations of intraspinal enterogenous cysts. Methods The MRI findings and related clinical data of 20 cases with enterogenous cysts proved by surgery and pathology were collected and analyzed. Results Nineteen lesions of 20 cases located in the subdural extramedullary space. Among which, 10 lesions occurred in the cervical segment, 4 lesions in the iunction of cervical and thoracic segments and 5 lesions in the thoracic segments. One lesion occurred in the thoracic spinal cord. All the lesions with well-defined margin presented with uniformity long T1 and long T2 signal in plain MRI and had no enhancement on the postcontrast images. 15 lesions showed sign of spinal cord incuneation. 4 cases associated other abnormity of the spinal column. Conclusion MRI can make the correct preoperative diagnosis according to the appearance, signal features and preferable location of enterogenous cysts.
