동시에 발생한 신장 혈관근지방종과 신세포암: 증례 보고

Abstract

Concurrent renal cell carcinoma (RCC) and angiomyolipoma (AML) is a very rare condition, especially in patients without underlying tuberous sclerosis. We present three patients with concurrent RCC and AML in the ipsilateral kidney. Concurrent RCC is difficult to differentiate radiologically from a non-fatty component of an AML because they share several imaging findings. However, several noticeable ra- diologic features are helpful in the diagnosis of suspected cases. This report of two cases highlights the radiologic features that distinguish RCC from non-fatty com- ponents of AML.
