ABSTRACT
Objective To retrospectively analyze the MRI findings of epithelioid angiomyolipoma (EAML) of the liver.Methods The MR findings in a series of 8 patients with pathologically proven liver EAML were retrospectively analyzed. Distribution of lesions, signal intensity characteristics, tumor vascularity,feeding arteries and draining veins, fat, hemorrhage, cystic necrosis and pseudocapsule formation were evaluated and correlated with pathology.Results A single lesion was found in each of the 8 patients.All eight lesions showed long T1,long T2 inhomogeneous signal,and high DWI signal. There was only 1 lesion presented with fat,3 lesions presented with hemorrhage. On the dynamic contrastenhanced MRI scan,all 8 lesions manifested as hypervascular with tortuous vasculature in 7 patients.Dilated feeding arteries and draining veins were seen in 5 patients. Conclusion Liver EAML has unique MR imaging features,exhibiting hyperwascular lesions with dialated,tortuous feeding arteries,and draining veins on DCE MRI,which could be helpful in the differential diagnosis of liver EAML.
