Metastatic melanoma with headaches. Preop planning for tumor resection. Limited stealth MRI of the brain for presurgical planning again demonstrates a large parenchymal lesion within the right frontal lobe with heterogeneous internal characteristics. The lesion previously showed prominent susceptibility artifact compatible with blood product. Adjacent to the left anterior aspect of this lesion again demonstrates a small triangular region of tissue with some degree of enhancement. There is significant surrounding edema, mild subfalcine herniation, and mass effect on the right lateral ventricle.Redemonstrated is a resection cavity at the convexity of the left frontal lobe which appears unchanged. An additional lesion within the right precuneus, now measuring no more than 9 x 8 mm, previously 9 x 7 mm.
1. Limited stealth MRI of the brain for presurgical planning. No significant interval change in the lesions in the right frontal lobe and right parietal lobe. 2. Stable left frontal lobe resection cavity.
