【摘要】：正病例1,患者男,34歲,10余天前無(wú)意間發(fā)現(xiàn)右大腿外側(cè)一腫塊,偶有酸痛不適。MR平掃示右側(cè)股外側(cè)肌見(jiàn)一梭形結(jié)節(jié),沿肌肉方向生長(zhǎng),約2.5cm×1.6cm,呈稍長(zhǎng)T1混雜T2信號(hào),邊界不清,T2WI示病灶內(nèi)可見(jiàn)低信號(hào)網(wǎng)狀影(圖1A),病變周?chē)梢?jiàn)水腫帶;增強(qiáng)掃描明顯強(qiáng)化,其內(nèi)網(wǎng)狀影不強(qiáng)化(圖1B)。MRI診斷為惡性腫瘤可能。行腫塊切除手術(shù)。術(shù)中見(jiàn)右股外側(cè)肌內(nèi)一韌性包塊,邊界欠清,表面較光滑,活動(dòng)性好。病理見(jiàn)梭形細(xì)胞與橫紋肌纖維間穿插分布,似"棋盤(pán)"樣,梭形細(xì)胞部分胖大,
[Abstract]:In case 1, a lump was found in the lateral right thigh by accident more than 10 days before the age of 34 years. Mr plain scan showed a fusiform nodule in the right lateral femoral muscle, which grew along the direction of the muscle, about 2.5cm 脳 1.6 cm, showing a slightly longer T1 mixed T2 signal intensity. Hypointensity reticular shadow could be seen on T2WI (Fig. 1), edema zone could be seen around the lesion, enhanced scan was obviously enhanced, and its internal reticular shadow was not enhanced (1B).MRI was possible to diagnose malignant tumor). Mass resection was performed. A ductile mass was found in the right lateral femoral muscle during the operation, the boundary was not clear, the surface was smooth and the activity was good. Histopathologically, it was found that the spindle cells interlaced with striated muscle fibers, like "chessboard", and the fusiform cells were partly fat.
