Male, 63 years old, history of renal cell carcinoma with solitary metastasis to the brain, status post surgery and postoperative SRS. Although dedicated pituitary sequences were not acquired on this exam, there has been a slight interval decrease in the size of the mildly enhancing sellar and suprasellar mass. The lesion demonstrates T2 hypointensity which may again represent hemosiderin staining or mineralization. Sequelae of prior transsphenoidal sellar surgery are again noted.Elsewhere intracranially, no pathologic enhancement is seen. No areas of edema or mass effect are detected. No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles are normal in size and morphology.An enhancing left masseter muscle lesion is partially visualized on only on the 3-D T1 post-contrast images. For further details, please refer to the CT of the neck tissues report from the same date.
