case_images: Through a left frontal craniotomy, lesion was approached, and complete resection was achieved. The biopsy was performed subsequently. The mass was brownish red, firm structure without necrosis, pigmentation, or hemorrhage [Figure 2].
case_images: Computed tomography scan at the end of 2 weeks after operation showing a new lesion in the right frontal lobe (red arrow).

case_images: CT scan at the end of 2 weeks after operation showed a new lesion in the right frontal lobe [Figure 3].
case_images: Three weeks after second resection did not reveal any evidence of residual or recurrent disease in computed tomography scan.
