【摘要】：目的:分析腹盆部孤立性纤维瘤(SFT)CT/MRI征象,提高对本病认识及诊断水平。方法:回顾性分析经手术病理证实11例腹盆部SFT的CT/MRI表现,7例行CT动态增强扫描,4例行MR动态增强扫描;分析肿瘤的位置,形态,大小(最大径),平扫密度及信号特点,动态增强特征,病灶周围有无迂曲血管影,病灶内有无点条状小血管影,边缘是否清晰。结果:11例共14个病灶;14个病灶表现为圆形或分叶状肿块,最大径约1.5~15.0cm;7例10个病灶CT表现为低密度,7个病灶有囊变或坏死,2个伴钙化;4例4个病灶MR平扫T1WI为等或低信号,T2WI为混杂信号或低信号,3个病灶伴囊变或坏死;12个病灶表现为动脉期中等或明显强化伴延迟强化,2个表现为动脉期轻度强化伴延迟强化;6个病灶增强后显示病灶周围迂曲血管影,10个病灶内可见点条状小血管影;10个病灶边缘清晰,4个病灶边缘不清晰。结论:腹盆部SFT的动态CT/MRI表现有一定多样性,但多数为富血供伴延迟强化的肿块,病灶周围迂曲血管影和病灶内点条状小血管影有助于诊断。
[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，
