Malignant neoplasm of unspecified part of unspecified bronchus or lung [C34.90] / Disorder of brain, unspecified [G93.9], Reason for Study: ^Reason: Hx of brain mets, on oral chemo, pls compare to previous and measure History: eval progression Motion artifacts degraded exam quality.The small (previously measured as 3mm) left anterior temporal lobe intra axial enhancing lesion is only demonstrated on axial reconstruction scan (about 2.5mm, series 1203, image 43/100). Due to motion artifact, the lesion is not seen on post Gad T1 axial scan. Non-enhancing right frontal and parietal skull lesions are again seen, unchanged since prior scan.Multifocal bihemispheric supra and infra tentorial brain parenchymal nodular susceptibility lesions are again seen, unchanged.There is no evidence of new abnormal enhancing lesion.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. The left anterior temporal small enhancing lesion does not show any significant interval change since prior scan.2. There is no evidence of new abnormal enhancement.3. Unchanged multifocal susceptibility lesions and skull lesions since prior scan.4. No evidence of acute ischemic or hemorrhagic lesion.
