摘要
目的探讨少见部位恶性纤维组织细胞瘤(MFH)的CT表现。方法搜集经病理证实的8例少见部位MFH患者的CT检查资料,就其发病部位、病灶形态大小、强化表现进行回顾性分析。结果 8例中,发病部位分别为左上颌骨、舌、食管、右肺、胃、胰腺、右肾上腺及左肾各1例。其中5例为体积较大软组织肿块,2例形态不规则,7例可见液化坏死,肿瘤恶性程度高,2例侵犯邻近组织。增强扫描5例呈明显延迟强化,坏死区不强化。结论MFH可发生于多部位,少见部位MFH与常见部位MFH影像表现既有其相似性,又有不同之处,影像学检查具有较高的诊断价值,确诊仍需结合病理及免疫组织化学。
Objective Explore the CT manifestations of malignant fibrous histiocytoma （MFH） in rare site. Methods A retrospective analysis of 8 cases with MFH＇s CT data in rare sites were collected and pathologically confirmed with re- spect to their sites, shapes, sizes, and enhanced manifestations. Results In the 8 cases, pathogenic sites were the left maxilla, tongue, esophagus, the right lungs, stomach, pancreas, the right adrenal and the left kidney. 5 cases were large soft tissue masses, 2 cases ＂shapes were irregular. In 7 cases of visible liquefaction necrosis, tumor malignant degree was high ,2 cases invaded neighboring tissues and enhanced scan in 5 cases was significantly delayed , necrotic area was not enhanced. Conclusion MFH can occur in many parts, the rare site MFH and the common site MFH＇s imaging have their similarities, but also have their differences, imaging examination has a high diagnostic value, but has to be combined with pathology and immunohistochemistry diagnosis for comprehensive analysis.
