【摘要】 目的:探討腹部及盆腔孤立性纖維瘤CT及MRI影像學(xué)表現(xiàn),并與病理特征對(duì)比。方法:選取30例接受CT檢查的腹部及盆腔孤立性纖維瘤患者,其中10例患者同時(shí)接受MRI檢查,觀察患者的影像學(xué)表現(xiàn),同時(shí)對(duì)病理特征進(jìn)行總結(jié)。結(jié)果:全部30例患者中,腹部孤立性纖維瘤、盆腔孤立性纖維瘤分別18例、12例。CT檢查結(jié)果發(fā)現(xiàn),30例患者的病灶密度表現(xiàn)為不均勻;給予增強(qiáng)掃描發(fā)現(xiàn),靜脈、實(shí)質(zhì)期呈現(xiàn)持續(xù)強(qiáng)化性病灶,23例患者動(dòng)脈期表現(xiàn)為迂曲條狀血管樣強(qiáng)化;該掃描檢查結(jié)果顯示,病灶不均勻強(qiáng)化較為明顯。給予MRI檢查發(fā)現(xiàn),其中有7例患者表現(xiàn)為T(mén)1WI低信號(hào),7例患者表現(xiàn)為T(mén)2WI不均勻稍高信號(hào),內(nèi)部伴隨稍低信號(hào),且為細(xì)條片信號(hào)??傮w病理檢查結(jié)果發(fā)現(xiàn),腫瘤具有完整的包膜,排列表現(xiàn)為多樣化,其構(gòu)成主要為梭形細(xì)胞,免疫組化CD34呈陽(yáng)性,瘤內(nèi)血管豐富。結(jié)論:腹部及盆腔孤立性纖維瘤的CT及MRI影像學(xué)表現(xiàn)具有一定的特征性,與病理特征相結(jié)合能讓臨床診斷的準(zhǔn)確性明顯提高。

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.

孤立性纖維瘤作為一種梭形細(xì)胞軟組織腫瘤,在臨床中的發(fā)病率并不高,并不常見(jiàn),臟層胸膜為最常見(jiàn)的發(fā)病部位,除此之外,發(fā)病部位還包括了肺、縱隔、腹膜、腹膜后腔、鼻咽以及眼眶等部位[1]。孤立性纖維瘤的腫塊表現(xiàn)為緩慢生長(zhǎng),發(fā)病初期患者并不會(huì)出現(xiàn)相關(guān)的臨床癥狀[2]。而隨著病情的逐漸發(fā)展,腫瘤不斷生長(zhǎng),則會(huì)導(dǎo)致患者出現(xiàn)一系列相關(guān)癥狀,如咳嗽、疼痛、呼吸困難、肺性骨關(guān)節(jié)病、副瘤綜合征等[3]。本研究主要對(duì)腹部及盆腔孤立性纖維瘤CT及MRI影像學(xué)表現(xiàn)與病理特征進(jìn)行分析,希望能為臨床診治提供依據(jù)。
