摘要

腎臟轉移性病灶在臨床可依病史、症狀和電腦斷層，超音波檢查得到診斷。文中複閱6例癌症病人，皆有腎臟和其他器官之多發性轉移。6例全接受電腦斷層攝影，有4例並接受超音波掃描。此兩種檢查雖無特異性；但若電腦斷層檢查呈邊緣不規則，病灶在對比劑注射後更為明顯，其密度均勻，且具輕度顯影增強；超音波檢查呈邊緣不規則，低回音實質性腫塊，腎中心竇回波不清，腎臟腫大；或體內多發性病灶時，當可臆測到腎臓囀移可能。文中並討論其他放射線檢查之發現。

Secondary renal tumor is a common postmortum findings but infrequent to detect clinically. Although ultrasound and Computed tomography (CT) are not specific, antemortum detection can be made by these modalities, if the primary malignancy or other metastases is known. Six oncology patients with multiple metastases are under study. Three of our cases have ultrasound guidance aspiration on the renal lesion. The other three are confirmed by clinical follow up. The ultrasound findings on four patients are hypoechoic solid renal lesions with irregular margin and poor definition of the central renal sinus. Six patients had CT scans and renal metastases are well defined lesion with homogenous density and slight enhanced after contrast injection. If the patient's clinical history is correlated with the above findings, renal metastases can be suspected. However, in questional cases percuteneous aspiration under ultrasound or CT guidance may be indicated.
