【摘要】：目的探讨肝脏炎性假瘤(IPTL)"厚壁圆环中心点"征的CT与MR表现特点。方法搜集经病理诊断(8例)及临床诊断(9例)的IPTL共17例常规肝脏CT及/或MR平扫及动态增强资料,综合分析病灶的形态及密度/信号表现。结果 (1)全部病例病变影像形态学均可分为两部分,即"厚壁圆环"和"中心点"。"厚壁圆环"表现:厚壁结构占病灶大部;部分/全部呈较明显类圆形,内外缘较清晰;呈多层不同厚度、欠规则同心环状,但整体厚度较均匀一致;呈渐进性强化。"中心点"表现:中心区仅占小部分或呈近似点状;每个病灶内可为一点或多点;各期无强化。(2)17例患者中单发11例,双发或多发6例、其中2例弥漫多发。(3)单发或散在多发"厚壁圆环中心点"14例,多个该结构融合(7例,其中部分病例为多发病灶中的部分融合)。(4)病变各部无固定CT密度值或MR信号特征。(5)病理证实的8例占同期纳入研究的IPTL病例的21.6%(8/37)。结论 "厚壁圆环中心点"征是部分IPTL的一个较特异影像征象,能否作为IPTL的一种独立影像分型有待进一步研究。
[Abstract]:Objective to investigate the CT and Mr features of the "central point of thick wall circle" in inflammatory pseudotumor of the liver (IPTL). Methods the CT and / or Mr plain scan and dynamic contrast-enhanced imaging of 17 cases of IPTL were collected from 8 cases of pathological diagnosis (n = 8) and 9 cases of clinical diagnosis (n = 9). Results the imaging morphology of all lesions could be divided into two parts: "thick wall ring" and "center point". The appearance of "thick wall ring": thick wall structure accounted for the majority of lesions. Some / all of them were round obviously, the inner and outer margin were clear, there were many layers of different thickness, irregular concentric ring shape, but the whole thickness was uniform and consistent, the whole thickness was more uniform and consistent, the "center point" showed that the central area was only a small part or an approximate point. There were one or more points in each lesion, 11 cases were single, 6 cases were double or multiple, 14 cases were single or scattered in the center point of thick wall circle, and 7 cases were fused with multiple structures, respectively, in each stage, 11 cases were single, 6 cases were double or multiple, 2 cases were diffuse or multiple, 14 cases were single or scattered in "center point of thick wall circle", and 7 cases were multiple fusion of this structure. Some of the cases were partial fusion of multiple lesions. (4) all parts of the lesions had no fixed CT density value or Mr signal characteristics. 5) 8 cases confirmed by pathology accounted for 21.6 / 837% of the IPTL cases included in the study at the same time. Conclusion the "central point of thick wall circle" is characterized by. A relatively specific image sign of some IPTL, Whether it can be used as an independent image classification of IPTL needs further study.
