 Motion degraded examination, specifically affecting the axial pre and post T1 sequences and the axial and coronal T2 sequences. Brain parenchymal morphology is within normal limits. Several scattered small foci of nonspecific FLAIR hyperintensity within the cerebral hemispheres which were not definitively seen on the prior examination. No edema or mass effect is detected. Diffusion-weighted images are within normal limits. There is no evidence to suggest intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricles are normal in size and morphology. Curvilinear enhancing structure in the right cerebellar hemisphere likely reflects a small developmental venous anomaly.
1. No evidence of an intracranial lesion.2. Scattered nonspecific foci of FLAIR hyperintensity may be seen in the setting of migraines. However, the differential considerations are numerous including prior inflammation, chronic small vessel ischemic disease, gliosis, etc.
