摘要

榮民總醫院放射線部自民國67年10月至71年10月間，共有七個腎臟畸型瘤(Renal hamartoma)之病例；所有病例皆接受電腦斷層攝影（Computed Tomography以下簡稱CT）且開刀治療；七例皆經病理證實為腎畸型瘤；本文就七例的電腦斷層攝影之發現與病理結果作對照討論，而提出報告，結果顯示對於含脂豐富的腎畸型瘤，CT何提供組織特異性的診斷(Tissue-specific diagnosis)，並且可正確地偵測到腫瘤的範圍及其併發症。

Renal Hamartoma (angiomyolipoma) is a rather uncommon benign renal tumor. Pathologically, Renal Hamartoma is composed of variable amount of three main tissues (1) smooth muscle (2) abnormal thick-walled blood vessels with tendency to hemorrhage and (3) mature adipose tissue.
Before the advent of computed tomography (CT), diagnosis of renal hamartoma depended on the recognition of fat within a renal mass on plain film. Because of its ability to discriminate small density differences, CT is ideally suited for detection of fat within the hamartoma.
This paper correlates the CT and pathological findings of 7 cases of angiomyolipoma in Veterans General Hospital from Oct. 1978 to Oct. 1982.
The results indicate that CT can provide the tissue-specific diagnosis of the adiposepredominant angiomyolipoma and can detect the complications of tumor.
