【摘要】：目的探討嬰兒型肝臟血管內(nèi)皮細(xì)胞瘤(IHH)的CT表現(xiàn)特征。方法回顧性分析16例經(jīng)手術(shù)病理及臨床診斷為IHH患兒的CT表現(xiàn)。結(jié)果 16例患兒中,單發(fā)病灶10例、多發(fā)病灶6例,均為肝內(nèi)富血供病灶,動脈期呈明顯環(huán)形強化,單發(fā)病變環(huán)形強化下方見向中心輻射的線狀強化。多發(fā)病灶中4例環(huán)形強化中心區(qū)域見類圓形片狀強化,靜脈期及延遲期強化范圍增大,1例多發(fā)病變強化類似于單發(fā)病灶強化方式,1例IHHⅡ型病灶小且多發(fā),動脈期表現(xiàn)為邊緣間斷細(xì)線狀強化,部分病灶線狀強化下方見小結(jié)節(jié)狀強化,靜脈期結(jié)節(jié)強化范圍增大,線狀強化范圍增大不明顯。結(jié)論IHH的CT表現(xiàn)具有一定特征性,其CT增強表現(xiàn)對本病的診斷更具意義。
[Abstract]:Objective to investigate IHH in infantile hepatic vascular endothelial cell tumor (IHH). Methods CT findings of 16 children with IHH diagnosed by pathology and clinic were analyzed retrospectively. There were 10 cases of single focus and 6 cases of multiple lesions, all of which were intrahepatic rich in blood supply, and the arterial phase showed obvious ring enhancement. Linear enhancement of central radiation was seen under circular enhancement of single lesions. In 4 cases, circular flake enhancement was seen in the central region of circular enhancement, and the range of enhancement in venous phase and delayed phase was increased. In one case, the enhancement was similar to that in the single lesion. In one case, the lesions of type 鈪，
