Planning for brain lesion treatment. There are bilateral frontal heterogeneous masses in the frontal lobes with extensive surrounding vasogenic edema. The largest of the lesions measures up to approximately 45 mm in the left frontal lobe. There is partial effacement of the left lateral ventricle and minimal midline shift to the right. Skin-based fiducial markers are present.
Treatment planning MRI demonstrates bilateral frontal lobe lesions with extensive vasogenic edema, compatible with metastases.
