2、例多發(fā)；邊界不清4例，邊界清晰2例；肝左葉3例，右葉2例，跨肝左、右葉l例。CT平掃均表現(xiàn)為低密度影，密度均勻者2例，密度不均者4例；動(dòng)態(tài)增強(qiáng)掃描動(dòng)脈期無(wú)明顯強(qiáng)化2例，輕一中度強(qiáng)化4例；門脈期呈進(jìn)一步中一重度強(qiáng)化6例，延遲期呈持續(xù)性強(qiáng)化5例，強(qiáng)化程度下降】例。另動(dòng)脈期病變內(nèi)見(jiàn)供血?jiǎng)用}1例，周圍見(jiàn)斑片狀異常強(qiáng)化1例；合并肝內(nèi)膽管擴(kuò)張1例。結(jié)論：HIMT的CT表現(xiàn)多樣，動(dòng)態(tài)增強(qiáng)掃描可充分反映病變的病理學(xué)特征，結(jié)合臨床資料，應(yīng)考慮到本病的可能；但最終確診仍依賴于病理和免疫組織學(xué)檢查?！娟P(guān)鍵詞】肝腫瘤；腫瘤，肌組織；體層攝影術(shù)，螺旋計(jì)算機(jī)【中圖分類號(hào)】R735．7；R730．262；R
