Özet
Angiomyolipoma (AML) of the kidney is the most common benign neoplasm encountered indaily clinical practice. Typical AMLs comprise three elements: mature adipose tissue, bloodvessels, and smooth muscle. Since classic AMLs contain considerable amount of adiposetissue, they are easily recognized on computed tomography (CT) and magnetic resonanceimaging (MRI) [1]. On the other hand, some AMLs comprise too little fat to be detected withunenhanced CT. These lesions are called ''fat poor AMLs'' that may be misdiagnosed asrenal cell carcinoma (RCC) on cross sectional imaging [2,3]. Angiomyolipoma with epithelialcysts (AMLEC) is an extremely rare subtype of fat poor AML, which contains epithelial-linedcysts. According to best of our knowledge imaging findings of AMLEC is very scarce and onlya total of 18 cases have been reported so far [4-8]. Herein, we aimed to report the MRIfeatures of AMLEC that resembles Bosniak category III lesion on MRI and emphasize thepotential role of dual gradient-echo imaging in detecting small amount of fat in AMLEC. © 2015 Published by Elsevier Masson SAS on behalf of the Editions francaises de radiologie.
