鞍旁16例占位病变定性误诊病例的MRI分析

MRI Diagnosis of Uncommon Space-occupying Lesions at Parasellar Region

本文总结了华山医院自1992年以来经手术和病理证实的鞍旁占位病变的MRI表现进行了分析,对鞍旁少见的及不典型的16例大部分定性误诊占位病变、就其MRI诊断和鉴别断要点,对照手术病理资料,进行了较深入,细致的研究和探讨,认为MRI三维成像是病变定位诊断的必要前提,而Gd-DTPA的应用,则有利于提高定性诊断的正确率。

Sixteen cases of uncommon parasellar space-occupying lesions verified by surgery and histology in Huashan Hospital were reviewed. We stressed on the MRI diagnosis and differential diagnosis in the uncommon and atypical parasellar space-occupying lesions. It was concluded that three dimensional imaging of MRI is an important predisposing factor in localization of the lesions. And Gd-DTPA enhanced MRI was helpful for making correct diagnosis.
