【摘要】：目的探討背部彈力纖維瘤的MRI表現(xiàn)和診斷價值。方法回顧性分析14例經(jīng)MRI及手術(shù)病理證實(shí)的背部彈力纖維瘤,其中3例接受患側(cè)肩部平掃,6例接受胸部平掃,5例接受胸部平掃及增強(qiáng),2例同時進(jìn)行了延遲增強(qiáng)掃描,分析其臨床及MRI表現(xiàn)特點(diǎn)。結(jié)果 14例均為女性,年齡47~78歲,病灶均位于背部肩胛下角區(qū)肌肉深面與胸壁之間的脂肪間隙內(nèi),14例中有9例為雙側(cè)病灶,除了臨床表現(xiàn)為雙側(cè)病變的5例外,4例為臨床表現(xiàn)為單側(cè)病變而胸部MR檢查發(fā)現(xiàn)對側(cè)有較小的亞臨床階段病灶。MR檢查共發(fā)現(xiàn)23個病灶。背部彈力纖維瘤在軸位及冠狀位呈扁丘狀,矢狀位呈類圓形;T1WI和T2WI均呈條紋狀間隔排列的骨骼肌樣低信號和脂肪樣高信號,脂肪抑制序列脂肪樣高信號被抑制,7個病灶內(nèi)見小的局灶性囊變;病變邊緣不整。增強(qiáng)掃描中5例9個病灶見條紋狀、斑片狀中等強(qiáng)化,2例4個病灶延遲增強(qiáng)掃描呈進(jìn)行性強(qiáng)化。結(jié)論中老年女性雙側(cè)或單側(cè)肩胛下角區(qū)扁丘狀腫塊,MRI表現(xiàn)為骨骼肌樣低信號與脂肪樣高信號條紋狀間隔排列、條紋狀及斑片狀中等強(qiáng)化者,應(yīng)考慮背部彈力纖維瘤。雙側(cè)同時檢查有利于發(fā)現(xiàn)亞臨床階段病變。
[Abstract]:Objective to investigate the MRI findings and diagnostic value of elastic fibroma in the back. Methods 14 cases of elastic fibroma of the back proved by MRI and pathology were retrospectively analyzed. Among them, 3 cases received plain scan of affected shoulder, 6 cases received chest plain scan, 5 cases received chest plain scan and 2 cases underwent delayed enhanced scan. The clinical and MRI features were analyzed. Results all the 14 cases were female, aged 4778 years. The lesions were located in the fat space between the deep muscle of the dorsal subscapular region and the chest wall in 9 of the 14 cases. Except 5 cases with bilateral lesions, 4 cases were unilateral lesions and 23 lesions were found in contralateral subclinical stage by Mr examination. The dorsal elastofibroma showed flat hillock in axial and coronal position, low signal intensity in skeletal muscle and high signal intensity in fat like in sagittal position with striped intervals on T _ 1WI and T2WI. Fat suppressor sequence was inhibited with high signal intensity, small focal cystic degeneration was found in 7 lesions, and the margin of the lesion was irregular. In contrast enhancement, 9 lesions were striped in 5 cases, and 4 lesions in 2 cases, with progressive enhancement in 2 cases. Conclusion in middle and aged women, bilateral or unilateral suprascapular region flat hillock mass should be considered for dorsal elastic fibroma in the presence of skeletal myoid hypointensity and fatty hyperintense stripe spacer, striped and patchy moderate enhancement. Bilateral simultaneous examination is beneficial to the detection of subclinical lesions.
