手指血管球瘤的MRI表现

目的探讨手指血管球瘤的MRI表现,以提高对本病的认识,减少误诊。方法回顾性分析经手术病理证实的11例手指血管球瘤的临床及MRI资料,11例均行MRI平扫,其中7例行MRI增强检查。结果11例中位于指甲下10例,1例位于指骨背侧;肿瘤边界清晰,在T1WI上呈等信号8例、稍低信号3例,在T2WI及PDWI上均呈高信号,增强扫描呈均匀明显强化。结论手指血管球瘤多具有典型的部位及MRI表现,MRI是诊断手指血管球瘤的首选方法。

MRI Appearances of Glomus Tumor in Finger

Objective To investigate the MRI appearances of glomus tumor in finger, to improve the understanding of this disease for the sake of misdiagnosis.Methods 11 cases of glomus tumor in finger proved by pathology were analysed retrospectively. All of the cages underwent MRI plain scan and 7 cases underwent MRI enhanced scan.Results 11 cases located at fingernail 10 cases, a case is located in the dorsal phalanges. The tumor borders were clear, MRI showed slightly lower intensities in three cases and isointensities in eight cases on T1 weighted images, and showed high intensities on T2 weighted images and PDWI. In the enhanced scans,all cases were apparent enhancement.Conclusion Finger glomus tumors are typical of the location and MRI appearances, MRI is the preferred method for diagnosing glomus tumors finger.
