Abstract

Renal epithelioid angiomyolipoma (EAML) is a rare tumor with the potential for malignant metastasis. EAML with local invasion is radiologically difficult to differentiate from renal cell carcinoma (RCC). The treatment of choice is surgery and there is no known effective management dealing with distant metastases. This case report described the imaging features of EAML and assessed the efficacy of TACE for the management of liver metastases, which, to our knowledge, no previous literature had addressed this issue.
