成人肢体梭形细胞/硬化性横纹肌肉瘤MRI诊断1例并文献复习
Journal of Imaging Research and Medical Applications（2023）
Abstract
目的:探讨梭形细胞/硬化性横纹肌肉瘤的影像特点及临床病理.方法:回顾分析东部战区海军医院1例成人大腿梭形细胞/硬化性横纹肌肉瘤MRI表现并做文献复习.结果:肿瘤T1WI呈等或稍低信号,T2WI上信号不均,以稍高信号为主,内部可见斑片状更高信号影,包膜呈低信号,增强后肿块呈不均质明显强化,动态增强曲线呈上升型,内部可见斑片状无强化区,包膜强化明显.肿块上下方可见斑片状较明显强化影,边界不清.结论:四肢的软组织肿瘤CT和MRI上表现为密度、信号不均,强化明显且不均匀,有坏死液化,无出血及钙化,应考虑到此病的可能.
