【摘要】 目的:探討腹部及盆腔孤立性纖維瘤CT及MRI影像學表現,并與病理特征對比。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例患者同時接受MRI檢查,觀察患者的影像學表現,同時對病理特征進行總結。結果: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檢查結果發現,30例患者的病灶密度表現為不均勻;給予增強掃描發現,靜脈、實質期呈現持續強化性病灶,23例患者動脈期表現為迂曲條狀血管樣強化;該掃描檢查結果顯示,病灶不均勻強化較為明顯。給予MRI檢查發現,其中有7例患者表現為T1WI低信號,7例患者表現為T2WI不均勻稍高信號,內部伴隨稍低信號,且為細條片信號。總體病理檢查結果發現,腫瘤具有完整的包膜,排列表現為多樣化,其構成主要為梭形細胞,免疫組化CD34呈陽性,瘤內血管豐富。結論:腹部及盆腔孤立性纖維瘤的CT及MRI影像學表現具有一定的特征性,與病理特征相結合能讓臨床診斷的準確性明顯提高。

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胞軟組織腫瘤,在臨床中的發病率并不高,并不常見,臟層胸膜為最常見的發病部位,除此之外,發病部位還包括了肺、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為緩慢生長,發病初期患者并不會出現相關的臨床癥狀[2]。而隨著病情的逐漸發展,腫瘤不斷生長,則會導致患者出現一系列相關癥狀,如咳嗽、疼痛、呼吸困難、肺性骨關節病、副瘤綜合征等[3]。本研究主要對腹部及盆腔孤立性纖維瘤CT及MRI影像學表現與病理特征進行分析,希望能為臨床診治提供依據。
