43 years, Female, lung cancer, history of brain metastases. There is mild T2 hyperintensity with susceptibility effect, which may represent mineralization or chronic blood products, involving the left posterior temporal white matter corresponding to a site of an enhancing lesion on prior study. Punctate foci of susceptibility effect in the left anterior temporal lobe as well as at the posterior medial left temporal-occipital junction are also seen and also correspond to sites of prior enhancing lesions. There is no abnormal parenchymal or meningeal enhancement on the current study to suggest active metastatic disease. No evidence of edema, intracranial mass, or mass effect. No evidence of acute ischemia. No midline shift or herniation. Ventricles are normal in size. Sella and orbits are grossly unremarkable. Paranasal sinuses and mastoid air cells are clear. Bone marrow signal and extracranial soft tissues are grossly unremarkable.
Previously seen enhancing metastatic lesions are no longer present, with residual susceptibility at the sites of prior lesions consistent with mineralization or chronic blood products. No new lesions or evidence of active intracranial metastatic disease.
