目的:通过分析椎管内肿瘤囊变的各种MRI表现,提高对椎管内肿瘤的诊断。方法:回顾性分析18例经手术及病理证实的椎管内肿瘤囊变的MRI表现。结果:神经鞘瘤囊变最常见,有8例,肿瘤呈稍长T1稍长T2信号,囊变区呈更长T1长T2信号;室管膜瘤囊变次之,有3例,肿瘤较大,呈腊肠状,沿脊髓纵轴生长,肿瘤内及两端常见坏死或空洞;脊膜瘤、淋巴瘤、神经母细胞瘤、畸胎瘤、表皮样囊肿各1例,肠源性囊肿2例。结论:椎管内肿瘤囊变具有一定的特征性MRI表现,对椎管内肿瘤的定性诊断有一定价值。
OBJECTIVE: To improve the diagnosis of intraspinal tumors by analyzing various MRI findings of intrasternal tumor cyst. Methods: The MRI findings of 18 cases of intraspinal canal tumor cystic degeneration confirmed by operation and pathology were analyzed retrospectively. Results: Schwannoma cystic degeneration was the most common, 8 cases, the tumor was slightly longer T1 slightly longer T2 signal, cystic area was longer T1 long T2 signal; ependymocystosis followed by 3 cases, the tumor was Large, was sausage-shaped, along the longitudinal axis of the spinal cord growth, tumor and both ends of the common necrosis or empty; meningioma, lymphoma, neuroblastoma, teratoma, epidermoid cysts in 1 case, enterogenous cysts 2 example. Conclusion: The intraspinal canal tumor has certain characteristic MRI manifestations, and it is of certain value to the qualitative diagnosis of spinal canal tumors.
