It showed a well-localized mass with circumscribed edges and progressive enhancement with gadolinium in sequence T1 (Figure 1a (Fig. 1)) and homogeneous enhancement in sequence T2 (Figure 1b (Fig. 1)).
a) Fibrous benign stroma (*) with dilated cavernous vessels and mature adipocyte cells in the periphery (**), H&E x4. b) The vessels filled with red blood cells (*). The endothelium and the stroma showed no signs of malignancy, H&E x10.
