目的总结滑膜肉瘤的影像学特征,比较CT与MRI诊断滑膜肉瘤的临床价值。方法 12例患者均接受CT及MRI检查,分析临床诊断肯定的滑膜肉瘤患者的CT及MRI检查资料。结果滑膜肉瘤的影像学表现复杂,典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块,磁共振T2WI/STIR像肿瘤内多呈稍高信号的“卵石”状结节,其间有低信号间隔,增强后结节不强化或轻度强化。结论滑膜肉瘤的影像学表现对本病的诊断起着不可估量的作用,CT和MRI综合评价有助于提高滑膜肉瘤的的诊断准确性。
Objective To summarize the imaging features of synovial sarcoma and to compare the clinical value of CT and MRI in the diagnosis of synovial sarcoma. Methods All 12 patients underwent CT and MRI examinations, and CT and MRI examination data of patients with definite diagnosis of synovial sarcoma were analyzed. Results The imaging findings of synovial sarcoma were complicated. The typical CT findings were deep, moderate or slightly uneven density of soft tissue mass. MRI T2WI / STIR showed a slightly higher signal in the tumor than in the “pebble” Like nodules, during which there is a low signal interval, enhanced nodules are not enhanced or mildly enhanced. Conclusion The imaging findings of synovial sarcoma play an inestimable role in the diagnosis of this disease. The comprehensive evaluation of CT and MRI can help to improve the diagnostic accuracy of synovial sarcoma.
