Abstract

笔者报道3例眼肌颗粒细胞瘤(GCT)的影像及病理表现。GCT的影像特点为肿块以肌腹为中心,CT上呈均匀等或稍高密度;常规MRI,相对于脑灰质,肿块于T1WI呈等信号、T2WI上呈低信号,增强扫描呈中等至显著强化;扩散加权成像呈等或稍低信号,平均表观扩散系数为0.60×10-3 mm2/s。GCT的病理特点为瘤细胞体积大,且细胞排列紧密,胞质充满嗜酸性颗粒,S-100表达强阳性。

眼外肌颗粒细胞瘤的CT和MRI表现
笔者报道3例眼肌颗粒细胞瘤(GCT)的影像及病理表现。GCT的影像特点为肿块以肌腹为中心,CT上呈均匀等或稍高密度;常规MRI,相对于脑灰质,肿块于T1WI呈等信号、T2WI上呈低信号,增强扫描呈中等至显著强化;扩散加权成像呈等或稍低信号,平均表观扩散系数为0.60×10-3 mm2/s。GCT的病理特点为瘤细胞体积大,且细胞排列紧密,胞质充满嗜酸性颗粒,S-100表达强阳性。
