椎管内畸胎类肿瘤的影像学诊断

The imaging diagnosis of teratoid tumor in spinal canal

目的:探讨椎管内畸胎类肿瘤的X线平片、椎管内造影、CT及MRI不同的影像学表现价值。方法:对12例经手术及病理证实的畸胎类肿瘤的临床、病理及影像学资料进行回顾性分析。结果:12例中,畸胎瘤6例、皮样囊肿4例、表皮样囊肿2例,均位于腰椎椎管内,10例肿瘤位于髓外硬膜下,2例位于髓内。结论:MRI是检查畸胎类肿瘤的最好手段,它较其它影像学检查方法对肿瘤的定性、定位更有帮助。

Objective： To evaluate the different imaging features of teratoid tumor in plain film, myelography, CT and MR. Methods： The clinical date, pathological and imaging findings of teratoid tumors proved surgically and pathologically in 12 cases were analyzed retrospectively. Results： 6 lesions were proved to be teratoma, 4 lesions be dermoid, 2 lesions be epidermoid cyst, which were aUlocated in spinal canal. Condusion： MRI is the best detecting method for teratoid tumors which can provide more details than other imaging findings.
