【摘要】：目的:研究脾脏炎性假瘤样滤泡树突细胞瘤的CT表现及病理学特征。方法:回顾性分析2例经手术和病理证实为炎性假瘤样滤泡树突细胞瘤的临床特点、CT表现及病理资料,并复习相关文献,总结炎性假瘤样滤泡树突细胞瘤的CT及病理学特征。结果:2例炎性假瘤样滤泡树突细胞瘤CT平扫表现为类圆形低密度肿块影,边界清晰,密度均匀,增强扫描动脉期示病灶边缘强化,门脉期病灶呈渐进性持续强化并向中央填充。病理:炎性假瘤样滤泡树突细胞瘤除了梭形细胞和炎细胞外,还有由少许多核巨细胞和组织细胞构成的伴有中心坏死的肉芽肿样改变;EBER原位杂交:EBER-ISH(+)。结论:脾脏炎性假瘤样滤泡树突细胞瘤CT动态增强扫描具有渐进性、持续性强化的特点,其CT表现与部分脾脏炎性假瘤相似,确诊需镜检及免疫组织化学检查。
[Abstract]:Objective: to study the CT findings and pathological features of spleen inflammatory pseudotumor-like follicular dendritic cell tumor. Methods: the clinical features, CT findings and pathological data of 2 cases of inflammatory pseudotumoral follicular dendritic cell tumor confirmed by operation and pathology were analyzed retrospectively. the CT and pathological features of inflammatory pseudotumoral follicular dendritic cell tumor were summarized. Results: two cases of inflammatory pseudotumor-like follicular dendritic cell tumor showed circular low density mass on CT plain scan, with clear boundary and uniform density. The edge of the lesion was enhanced in the arterial phase of enhanced scan, and the lesion in portal vein phase showed progressive continuous enhancement and filling into the center. Pathology: inflammatory pseudotumor-like follicular dendritic cell tumor, in addition to fusiform cells and inflammatory cells, there are many granulomatous changes with central necrosis, which are composed of many nuclear giant cells and tissue cells. EBER in situ hybridization: EBER-ISH (). Conclusion: CT dynamic contrast-enhanced scan of inflammatory pseudotumor-like follicular dendritic cell tumor of spleen has the characteristics of gradual and continuous enhancement. The CT findings of inflammatory pseudotumor of spleen are similar to those of some inflammatory pseudotumor of spleen. Microscopic examination and histochemical examination are needed for the diagnosis of inflammatory pseudotumor of spleen.
