Epithelioid angiomyolipoma of the liver: Cross-sectional imaging findings of 10 immunohistochemically-verified cases

Figure 3 17-year-old girl with epithelioid angiomyolipoma in right lobe of liver (the patient had a history of tuberous sclerosis complex, patient 5). A: Non-enhanced CT scan shows homogeneous hypoattenuating lesion in segment V/VII/VIII; B: Contrast-enhanced CT scan shows inhomogeneous enhanced lesion with opacification of central vessels (arrow) on the arterial phase; C: The slight enhanced outer rim (arrow) around the inhomogeneous enhancement lesions is shown on portal phase contrast-enhanced CT; D: Immunohistochemical staining for HMB-45 shows diffusely positive staining in tumor cells within the cytoplasm (EnVision, × 100).
