摘要
目的分析并总结胸部孤立性纤维瘤(solitary fibrous tumor,SFT)的CT特点。方法回顾性分析16例SFT患者的临床资料,分析其CT表现。结果 16例SFT中1例CT表现为以宽基地与纵膈胸膜相连,11例以宽基地与侧胸膜相连,3例表现为胸腔内巨大肿块,1例位于左侧心膈角处且与邻近胸膜关系密切。病灶直径范围约2.5~15.0 cm;类卵圆形病灶11例,5例呈不规则团块状,且局部境界欠清晰。CT平扫呈等密度,其中2例见弯条状钙化。增强后动脉期轻到中度强化,3例可见弯曲血管显示,随着时间延长,病灶进一步强化,区域增大,6例密度不均匀,其中3例呈"地图样"表现,3例病灶伴有邻近肺组织膨胀不全。9例出现胸膜尾征表现。10例与邻近胸膜呈钝角关系。结论胸部SFT的CT表现特点:单发病灶,可有"胸膜尾征",增强后早期轻到中度强化,可见弯曲血管显示,随着时间延长,病灶进一步强化,区域增大,部分可见"地图样"表现,综合其影像学特征及临床资料有助于胸部SFT的诊断。
Objective To analyze and summarize the CT features of solitary fibrous tumors in thorax.Methods The clinical data of 16 patients with SFT were retrospectively analyzed and their CT manifestations were analyzed.Results In all patients,1 case was connected to the mediastinal pleura with a wide base,11 cases were connected to the lateral pleura with a wide base,3 cases showed a huge mass in the chest cavity,and 1 case was located at the left diaphragmatic angle and closely related to the adjacent pleura.The diameter of the lesion ranged from 2.5 cm to 15.0 cm.There were 11 cases with ovaloid lesions,and 5 cases with irregular mass and unclear local boundary.CT scan showed equal density,and curved strip calcification was found in 2 cases.In the arterial stage after enhancement,mild to moderate enhancement was observed,and curved blood vessels were observed in 3 cases.With the extension of time,the lesion further strengthened and the area increased,and the density was uneven in 6 cases,among which 3 cases presented"MAP image",and 3 cases were accompanied by adjacent lung tissue insufficiency.Tail pleural sign was found in 9 cases,and obtuse angles with adjacent pleura were observed in 10 cases.Conclusion Solitary fibers tumor in thorax has several CT features:single lesion,may have"pleural tail sign",the early mild to moderate enhancement with visible curved vessels;with the extension of time,lesions further strengthen and area increases,part of them have the"MAP image"performance.Integration the imaging features and clinical data is helpful to diagnose the solitary fiberous tumor in thorax.
