 Limited examination done for preoperative planning. Motion degraded postcontrast images.There is an enhancing mass in the right posterior frontal lobe measuring 2.0 x 2.2 cm (series 301, image 148). There is minimal localized mass effect. An additional smaller enhancing lesion in the left precentral gyrus measures 0.6 x 0.6 cm (series 301, image 132). There is surrounding high T2 signal compatible with vasogenic edema in the right frontoparietal lobes and left frontal lobe.The ventricles and sulci are mildly prominent compatible with age-related volume loss, aside from the areas of sulcal effacement in the areas of the masses. The cisterns remain patent. There is no midline shift or mass effect. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. A left maxillary retention cyst is noted, previously noted to be T1 hyperintense on outside imaging.
Enhancing lesions in the bilateral posterior frontal lobes with surrounding vasogenic edema are most consistent with metastatic disease.
