摘要
目的 探讨脊髓成血管细胞瘤的MRI特征。材料与方法 5例经手术病理证实的脊髓成血管细胞瘤患者 ,男 1例 ,女 4例 ,年龄 2 5～ 63岁 ,平均 3 7岁。全部采用超导MRI系统检查。结果 5例成血管细胞瘤发生于颈髓和胸髓。根据其MRI表现 ,可分为大囊小结节型和实质性肿块型。在增强MRI上 ,壁结节及实性结节肿块皆呈明显均匀强化。 3例在肿块内及周围可见流空血管。结论 脊髓成血管细胞瘤的MRI特征为 :易囊性变 ,囊结节及实性部分明显强化并可见流空血管。
Objective To explore MRI features of spinal hemangioblastomas.Materials and Methods MRI was performed in 5 patients (1 male, 4 females, aged 25～63 years with a mean of 37) with pathologically proved spinal hemangioblastomas.Results The hemangioblastomas occurred in cervical and thoracic spinal cord in all 5 patients. Based on the MRI manifestations the lesions could be divided into two types: (1) large cyst with small mural nodules, and (2) solid mass. All of the solid masses and mural nodules displayed marked and homogeneous enhancement on MRI after the injection of Gd DTPA. Vascular signal void within and around the mass was seen in 3 patients.Conclusion The MRI features of the spinal hemangioblastoma are cystic degeneration, marked enhancement of the solid mass and the mural nodule within the cyst, and vascular signal void sign.
