Left parietal brain tumor, operative planning. Examination is limited to sequences for operative planning and intraoperative guidance. Fiducial markers are in place. Again seen is an infiltrative, enhancing mass within the left parietal calvarium that measures up to 50 mm with mild epidural extension. There is minimal associated mass effect upon the underlying left parietal lobe. No intraparenchymal lesions are seen.There is an additional more nonspecific punctate focus of enhancement in the left frontal calvarium, which appears to be present on prior and may represent an additional lesion (axial post gadolinium series 401 133/196).
Examination obtained for operative planning again demonstrating enhancing mass involving the left parietal calvarium with mild epidural extension and consistent with metastatic disease. There is a punctate additional focus of enhancement in the left frontal calvarium, which may represent an additional lesion.
