【摘要】：目的:分析腹盆部孤立性纖維瘤(SFT)CT/MRI征象,提高對本病認(rèn)識及診斷水平。方法:回顧性分析經(jīng)手術(shù)病理證實(shí)11例腹盆部SFT的CT/MRI表現(xiàn),7例行CT動態(tài)增強(qiáng)掃描,4例行MR動態(tài)增強(qiáng)掃描;分析腫瘤的位置,形態(tài),大小(最大徑),平掃密度及信號特點(diǎn),動態(tài)增強(qiáng)特征,病灶周圍有無迂曲血管影,病灶內(nèi)有無點(diǎn)條狀小血管影,邊緣是否清晰。結(jié)果:11例共14個病灶;14個病灶表現(xiàn)為圓形或分葉狀腫塊,最大徑約1.5~15.0cm;7例10個病灶CT表現(xiàn)為低密度,7個病灶有囊變或壞死,2個伴鈣化;4例4個病灶MR平掃T1WI為等或低信號,T2WI為混雜信號或低信號,3個病灶伴囊變或壞死;12個病灶表現(xiàn)為動脈期中等或明顯強(qiáng)化伴延遲強(qiáng)化,2個表現(xiàn)為動脈期輕度強(qiáng)化伴延遲強(qiáng)化;6個病灶增強(qiáng)后顯示病灶周圍迂曲血管影,10個病灶內(nèi)可見點(diǎn)條狀小血管影;10個病灶邊緣清晰,4個病灶邊緣不清晰。結(jié)論:腹盆部SFT的動態(tài)CT/MRI表現(xiàn)有一定多樣性,但多數(shù)為富血供伴延遲強(qiáng)化的腫塊,病灶周圍迂曲血管影和病灶內(nèi)點(diǎn)條狀小血管影有助于診斷。
[Abstract]:Objective: to analyze the (SFT) CT/MRI features of abdominal and pelvic solitary fibroma and to improve the understanding and diagnosis of the disease. Methods: the CT/MRI findings of 11 cases of abdominal and pelvic SFT confirmed by operation and pathology were analyzed retrospectively. the dynamic contrast-enhanced scan of CT was performed in 7 cases and dynamic contrast-enhanced scan of MR in 4 cases. The location, shape, size (maximum diameter), plain scan density and signal characteristics, dynamic enhancement characteristics, whether there were circuitous vascular shadow around the lesion, whether there were punctate small vessel shadow in the lesion, and whether the edge was clear or not were analyzed. Results: a total of 14 lesions were found in 11 cases, 14 lesions were round or lobulated masses, 10 lesions with maximum diameter of 1.5 cm 鈮，
