 Axial T2 precontrast and axial T1 postcontrast images were acquired for treatment planning purposes. Multiple fiducial markers are in place. Multiple abnormal brain lesions are identified. There is a round enhancing lesion within the right posterior frontal lobe involving the hand motor area of the precentral gyrus extending anteriorly abutting the junction with the right superior frontal gyrus measuring 16 x 17 mm in the axial plane with surrounding vasogenic edema. There is an additional enhancing lesion within the posterior right temporal lobe which measures 9 x 10 mm in the axial plane which lacks significant surrounding edema. There are additional subcentimeter foci of punctate enhancement within the left superior frontal gyrus, right putamen, and left insula. There are several punctate foci of susceptibility artifact within the right posterior temporal lobe. There are multiple foci of abnormal enhancement within the bilateral cerebellar hemispheres with associated susceptibility artifact suggesting associated microhemorrhage. Fluid is present within the right greater than left mastoid air cells. Mild mucosal thickening is present within the paranasal sinuses.The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are grossly intact.
1.Multiple supratentorial and infratentorial brain metastases with the largest in the right posterior frontal lobe.2.Paranasal sinus mucosal thickening and fluid within the right greater than left mastoid air cells.
