Figure 1. Magnetic ressonance with axial T1WI image in phases before contrast (A), arterial (B), Portal (C) and Equilibrium (D), showing a heterogenous nodule, hypervascularized, with peripheral progressive highlight due to contrast at the retroperitoneum, measuring 2.4x2.1cm.
Figure 2
Figure 2. Magnetic resonance images (ECO Gradient sequences GRE) T1W1 inside and outside of phase (A and B) and in T2 with and without fat suppression (C and D); they show sparse areas of signal loss corresponding to lipomatous foci.

A) triphasic tumor, including mature adipose tissue, blood vessels with thickened wall and smooth muscle cells; B) component of elongated smooth muscle cells irradiating from gibbous vessels walls, permeating adipose tissue; c) angiomiolipoma, interface between mature fat cells and smooth muscle cells without atypia.
