摘　　要：目的提高对少见部位巨大滑膜肉瘤(SS)的认识和影像诊断水平。方法通过1例经病理证实的腹壁巨大滑膜肉瘤的症状、临床表现及CT、MRI等影像表现,结合SS相关文献,回顾分析SS影像特征。结果腹壁巨大SS的影像学表现与四肢关节典型的SS既有相似性,又有不同之处;SS出现“三重”信号征、瘤周水肿、“筋膜尾征”等往往提示其侵袭性强,术后易出现局部复发和转移;肿瘤SS“钻孔样”生长趋势可能对其诊断有一定的提示作用。结论少见部位巨大SS与典型部位SS的影像学特征有一定的相似性,亦有不同之处。Objective To improve the recognition and imaging diagnosis of giant synovial sarcoma(SS)in rare sites.Methods The clinical manifestations and CT and MRI findings of a case of giant abdominal wall SS confirmed by pathology were retrospectively analyzed,and the related literature was reviewed.Results The typical MRI findings of SS of the abdominal wall are not significantly from those of limb joints.The“triple”signal sign,peritumoral edema and“fascial tail sign”of SS often indicate that it is aggressive and prone to local recurrence and metastasis after surgery.The manifestations of“triple sign”,“nodular accumulation sign”and“liquid-liquid equilibria”are conducive to the diagnosis of SS.The“drilling-like”growth trend can be used as image reference for the diagnosis of SS,especially in the intraperitoneal cavity and diplomatic area.Conclusion The imaging features of giant SS in rare sites are similar to those in typical sites,and attention should be paid to the identification of the differences.
