Benign neoplasm of brain, unspecified [D33.2], Reason for Study: ^Reason: h/o low grade astrocytoma History: surveillance Redemonstration of the right centrum semiovale nonenhancing relatively well circumscribed T2/FLAIR high signal intensity lesion without surrounding edema, unchanged in terms of MR signal characteristics and maximum diameter [22.9mm(CC) x 14.4mm(RL) x 22.1mm(AP)] since prior scan.The ventricles, sulci and cisterns are unremarkable. There is no intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Unchanged in size and MR characteristics of the right centrum semiovale lesion since prior scan.No new abnormal enhancing lesion seen.No acute ischemic or hemorrhagic lesion.
