摘要
目的探讨MRI在颅内血管母细胞瘤诊断中的应用价值。方法18例经手术病理证实的颅内血管母细胞瘤患者,男11例,女7例,均行MRI平扫+增强检查,分析其MRI征象。结果17例血管母细胞瘤位于后颅窝。14例表现为大囊小结节型,结节强化明显;4例表现为实质型。13例瘤内或瘤周可见血管流空信号。MRI术前诊断准确率为88.9%(16/18)。结论MRI是术前诊断血管母细胞瘤的有效检查方法。
Objective To discuss the applied value of MRI in the diagnosis of intracranial hemangioblastoma(ICH).Methods Eighteen patients (male 11 and female 7)with surgically and pathologically proved ICHs underwent MR imaging before and after administration of contrast medium (Gd-DTPA).All the MRI data from 18 patients with ICHs were analyzed retrospectively.Results Among 18 cases with ICHs,17 cases whose lesions located in posterior cranial fossa,14 cases whose lesions presented as shape of big cyst and small node with obvious enhancement,and 4 cases whose lesions presented as solid mass.The intratumoral or peritumoral blood vessel flow-void-signals were found in 13 cases.The preoperative definitive diagnosis rate of MRI was 88.9%(16/18).Conclusion MRI is an effective modality in preoperative diagnosis of ICH.
