3 month follow-up of brain lesion Peripherally enhancing left occipital lesion has increased in size and now measures 1.0 x 1.2 x 1.5 cm (image 36, series 1201; image 172, series 1202), previously 0.6 x 0.8 x 1.0 cm. The surrounding T2/FLAIR hyperintensity has increased, likely representing a combination of edema and gliosis. No new intraparenchymal mass lesion or new abnormal areas of enhancement are identified.Status post right frontal craniectomy. The underlying confluent increased T2 signal is seen throughout the right frontal lobe is unchanged. Periventricular increased T2/FLAIR signal is also unchanged and may be treatment related small vessel ischemic disease.No diffusion restriction is seen to suggest acute ischemia. No susceptibility weighted artifact is seen to suggest intracranial hemorrhage. No abnormal areas of enhancement are seen. The CSF spaces are appropriate for the patient's stated age with no midline shift. Normal vascular flow voids are present in the major intracranial vasculature.Enhancing right temporal bone lesion is unchanged from the prior study.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Increase in size of peripherally enhancing left occipital lesion with increase in surrounding edema/gliosis.2.No change in right temporal osseous metastasis.3.Right frontal lobe postsurgical changes.
