We report MR findings in a case of a giant cell reparative granuloma involving the temporal lobe in a middle-aged man. On MR images, most of the mass was hypointense on T1-weighted images, hypointense on T2-weighted images, and mildly enhanced on postcontrast T1-weighted images. The hypointensity on T2-weighted images corresponded to areas of hemorrhage and hemosiderin deposition on pathologic correlation.
我们报告了一例中年男性颞叶巨细胞修复性肉芽肿的磁共振成像(MR)表现。在MR图像上,大部分肿块在T1加权像上呈低信号,在T2加权像上呈低信号,在增强后的T1加权像上轻度强化。T2加权像上的低信号在病理对照中对应于出血和含铁血黄素沉积区域。
