血管肉瘤四例并文献复习

Four Cases of Angiosarcoma and Literature Review

目的探讨血管肉瘤(angiosarcoma)的影像表现及相关组织病理学特点,以提高对本病的认识与诊断水平。方法回顾性分析经病理证实的4例原发性血管肉瘤的临床及影像表现,并结合相关文献分析总结。结果4例血管肉瘤中,3例表现为肿块型,1例表现为弥漫结节型,肿块型表现为向心或离心性强化,弥漫结节型表现为环形强化,其中1例发现时已有转移。结论血管肉瘤的临床影像及病理表现有一定的特征性,结合临床资料可提高诊断率。

Objective To explore the imaging features and related histopathological features of angiosarcoma in order to improve the recognition and diagnosis of angiosarcoma.Methods The clinical and imaging findings of 4 cases of primary angiosarcoma confirmed by pathology were analyzed retrospectively and the literatures were reviewed and summarized.Results Of the 4 cases of angiosarcoma,3 cases showed mass type,1 case showed diffuse nodule type,the mass type showed centripetal or centrifugal enhancement,diffuse nodule type showed circular enhancement,and 1 case had metastasis at the time of discovery.Conclusion The clinical,imaging and pathological manifestations of angiosarcoma had certain characteristics,and the diagnosis rate could be improvided in combination with clinical data.
