66 years, Female, history of TIA with worsening left facial droop. No restricted diffusion to suggest acute ischemia. No findings to suggest acute intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Few scattered foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with minimal chronic small vessel ischemic changes. Again seen are scattered foci of susceptibility effect throughout the brain. Unchanged relatively large focus of susceptibility in the left cingulate gyrus. Again seen is linear susceptibility effect along the anterior and the posterior interhemispheric fissures as well as the falx, suggestive of remote subarachnoid and subdural hemorrhage and residual siderosis. Foci of susceptibility artifacts are also seen in the cerebellum. These all are unchanged since 10/15/2015.Major flow-voids are preserved. There is diffuse heterogeneous of the bone marrow signal which may be related to known leukemia.
1. No evidence of acute infarct.2. Multiple scattered chronic microhemorrhages in the brain parenchyma as well as siderosis related to likely prior subarachnoid and subdural hemorrhages as seen previously on 10/15/2015.3. Diffuse heterogeneous bone marrow which may be related to known leukemia.
