case_images: (a and b) Computed tomography scan showing an osteolytic lesion of the left frontal bone, extending to the surrounding subgaleal soft tissues. An irregular left frontal lobe mass, below the bone defect, was also present. (c) Three-dimensional computed tomography scan showing the frontal bone defect. (d) Magnetic resonance examination showing the lesion with an irregular increased signal intensity on T1-weighted images and the coexistence of low- and high-signal components, suggesting different phases of intratumoral hemorrhage. After gadolinium administration, a slight peripheral enhancement was evident. (e) Postoperative magnetic resonance imaging revealing the contrast enhancement of the dural layer with no residual tumor. (f) Three-dimensional computed tomography scan showing the reconstruction of the bone defect
