60-year-old female status post seizure. Exam is limited secondary to motion artifact. No susceptibility artifact to indicate intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration.There is an area in the left posterior temporo-occipital white matter which demonstrates decreased signal on dADC and increased signal on eADC without corresponding changes on diffusion or FLAIR imaging. This likely represents artifact on the ADC maps.Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical, periventricular white matter, and right thalamus which are nonspecific, but compatible with chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age.No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. Mild chronic small vessel ischemic changes.2. Decreased signal on the ADC maps in the left posterior temporal occipital white matter without corresponding diffusion or FLAIR changes. These findings are likely artifactual, but could be confirmed with short-term follow-up MRI including coronal diffusion images. Please correlate with clinical symptoms.
