Intraoperative photos showing. (a) Brain MRI sequence with GD in T1 showing lesion with homogeneous enhancement contrast in scalp associated with bone invasion and compressive effect on the adjacent brain parenchyma. The mass enhanced homogeneously. (b) Delimitation of skin incision around the tumor on the right, midline delimitation on the left. (c) Tumor measures after the tumor resection. (d) Cranioplasty with bone cement.

T1-weighted MRI sequences before and after administration of intravenous gadolinium demonstrated the mass in the scalp, subcutaneous tissues, and skull, compressing the underlying brain. The mass enhanced homogeneously (Figure 1(a)). He had a mass lesion in the right frontal region with 11 x 10 x 5 cm, adherence to deep tissue planes, and firm and rubbery consistency (Figures 1(b) and 1(c)). We performed duraplasty with fascia lata and cranioplasty with appropriate bone cement (Figure 1(d)).

There was no evidence of dural invasion; lesions were observed within small vessels and infiltrating bone structures (Figures 2(a), 2(b), 2(c), and 2(d)).
