摘要

臺大醫院腸胃科過去4年間，使用卽時性直線形腹部超音波掃描儀器，總共收集了87例轉移性肝癌患者之超音波圖像。男性52例，女性35例，年齡分佈於20歲至80歲間。其原發部位主要為鼻咽癌、胰臟癌、大腸癌、胃癌、乳房癌及肺癌。
74例(85.1%)患者之肝臟轉移病灶屬多發性，其中66例犯及兩葉。低囘音結節病灶較常見(39.1%)特別是直徑小於5公分者(47.8%)。反之，直徑大於5公分者，91.3%屬高囘音病灶。全部115個病灶中，有33 (29.5%)個病灶呈現靶心型圖像。一般說來，沒有一種原發性癌症之轉移性肝臟病灶具有特定之起音波圖懷；但是大腸癌之病灶，不論大小，通常顯現高囘音影像。
12例(13.8%)患者之病灶中呈現囊泡變化。另有4例(4.6%)患者高囘音之病灶上出現鈣化斑點。
9例病人接受2次以上超音波追踪檢查，我們發現其起音波病灶圖像之燮化，與其臨床情況之轉變相吻合。

Using high-resolution linear-array real-time scanners, abdominal ultrasonography was performed in 87 cases with metastatic liver cancers from various primary origins. There were 52 males and 35 females with ages ranging from 20 to 80 years. Seventy-four (85.1%) showed multiple lesions, and 66 (75.9%) had involvement of both lobes. Hypoechoic nodules were found most frequently (39.1%), especially in those cancers with diameters of less than 5cm (47.8%). On the other hand, 91.3% of those lesions with diameters greater than 5cm were hyperechoic. Bull's-eye echofeature was found in 29.5% of the lesions. The sonographic patterns lacked specifity in defining the primary origins. However, lesions metastasized from colorectal organs usually showed hyperechoic features, even though the lesion was small. Twelve (13.8%) cases were noted to have cystic changes and four (4.6%) displayed calcification over their hyperechoic nodules. Serial observations in 9 patients disclosed that follow-up changes of sonographic features correlated well with their clinical conditions.
