Figure 4.

Classic angiomyolipoma. Axial unenhanced CT image (a) demonstrates a typical fat-containing angiomyolipoma (arrow). Axial T1 weighted dual-echo in-phase (b) and opposed-phase (c) MR images show an India-ink artefact at the border of the mass and the renal parenchyma on opposed-phase images (double arrows). The mass (arrow) shows early enhancement in the corticomedullary phase (d) of the axial gradient-echo fat-suppressed T1 weighted MR image after gadolinium administration. Note two renal cysts adjacent to the AML (asterisks).
