【摘要】 目的:探讨腹部及盆腔孤立性纤维瘤CT及MRI影像学表现,并与病理特征对比。方法:选取30例接受CT检查的腹部及盆腔孤立性纤维瘤患者,其中10例患者同时接受MRI检查,观察患者的影像学表现,同时对病理特征进行总结。结果:全部30例患者中,腹部孤立性纤维瘤、盆腔孤立性纤维瘤分别18例、12例。CT检查结果发现,30例患者的病灶密度表现为不均匀;给予增强扫描发现,静脉、实质期呈现持续强化性病灶,23例患者动脉期表现为迂曲条状血管样强化;该扫描检查结果显示,病灶不均匀强化较为明显。给予MRI检查发现,其中有7例患者表现为T1WI低信号,7例患者表现为T2WI不均匀稍高信号,内部伴随稍低信号,且为细条片信号。总体病理检查结果发现,肿瘤具有完整的包膜,排列表现为多样化,其构成主要为梭形细胞,免疫组化CD34呈阳性,瘤内血管丰富。结论:腹部及盆腔孤立性纤维瘤的CT及MRI影像学表现具有一定的特征性,与病理特征相结合能让临床诊断的准确性明显提高。

CT and MRI Findings and Pathological Features of Solitary Abdominal and Pelvic Fibroma/SONG Ping. //Chinese and Foreign Medical Research, 2020, 18(15): -70

[Abstract] Objective: To study the CT and MRI findings of solitary fibroma of abdomen and pelvis, and to compare them with pathological features. Method: A total of 30 patients with solitary fibroma of abdomen and pelvis by CT were selected, 10 of them were examined by MRI at the same time. The imaging features of the patients were observed and the pathological features were summarized. Result: Of the 30 patients, 18 were abdominal solitary fibroma and 12 were pelvic solitary fibroma. The results of CT showed that the density of lesions in 30 patients was not uniform; the enhanced scanning showed that the continuous enhanced lesions in vein and parenchyma phase and tortuous vascular like enhancement in artery phase in 23 patients; the scanning results showed that the uneven enhancement of lesions was more obvious. MRI examination showed that 7 patients showed low signal on T1WI, 7 patients showed uneven and slightly high signal on T2WI, with slightly low signal inside, and thin slice signal. The results of general pathological examination showed that the tumor had a complete envelope and diversified arrangement. The main components of the tumor were spindle cells, CD34 was positive in immunohistochemistry, and there were abundant blood vessels in the tumor. Conclusion: CT and MRI findings of solitary fibroma of abdomen and pelvis have certain characteristics, which can improve the accuracy of clinical diagnosis by combining with pathological features.

孤立性纖维瘤作为一种梭形细胞软组织肿瘤,在临床中的发病率并不高,并不常见,脏层胸膜为最常见的发病部位,除此之外,发病部位还包括了肺、纵隔、腹膜、腹膜后腔、鼻咽以及眼眶等部位[1]。孤立性纤维瘤的肿块表现为缓慢生长,发病初期患者并不会出现相关的临床症状[2]。而随着病情的逐渐发展,肿瘤不断生长,则会导致患者出现一系列相关症状,如咳嗽、疼痛、呼吸困难、肺性骨关节病、副瘤综合征等[3]。本研究主要对腹部及盆腔孤立性纤维瘤CT及MRI影像学表现与病理特征进行分析,希望能为临床诊治提供依据。
