摘要

複閱腎腫瘤病例，榮民總醫院於民國70年及71年兩年間，藉超音波檢查診斷為腎實質腫瘤，並經病理證實者凡36例，各種腎實質腫瘤，有其超音波圖形上的特徵；腎細胞瘤大多數(68%)為不均勻(heterogeneous)且高迴音性(hyper-echoic)腫瘤，低迴音性腫瘤僅占14%；畸胎瘤兩例均呈現混合型(mixed-type)迴音，而且腫瘤內脂肪成分所造成極強的高迴音區與明顯的腫瘤後壁迴音衰減為其特徵；移行上皮細胞癌位於腎竇內，可將腎竇撐開，而腫瘤本身多半為低迴音區(50%)或等迴音區(34%)。威氏瘤(Wilm's tumor)及神經胚芽瘤(neuroblastoma)是小孩最常犯的腎腫瘤；前者位於腎臟內，一般外緣平滑整齊，內部多為均勻高迴音(67%)腫瘤；後者源於腎上線，外緣極不規則，內部為不均勻的高迴音腫瘤。

並列摘要

72 cases of solid renal lesion were studied by renal sonography in our department. The result of 36 cases were correlated with pathology.
The ultrasound diagnosis of renal solid tumor is based on (1) tumor echopattern (2) localization (3) clinical symptom and sign, in our cases, the echogenicity of renal cell carcinoma is almost always heterogeneous (68%) and hyperechoic (50%), only rare is hypoechoic (14%); two cases of hamartoma are all mixed-type echogenicity. The fat content could produce characterized dense hyperechoic area, and strong posterior sound attenuation; Wilms tumor is derived from kidney, commonly shows smooth contour, homogeneous and hyperechoic internal echo. Neuroblastoma arises from adrenal gland. It usually has irregular contour and heterogeneous, high internal echo.
