Worsening headache with known white matter abnormality on previous MRI. A number of scattered punctate hyperintense T2/FLAIR lesions are somewhat better seen due to the 3 Tesla imaging technique, but these were all likely present on the previous exam, and do not appear to have significantly changed.No diffusion restriction is seen to suggest acute ischemia. No susceptibility weighted artifact is seen to suggest intracranial hemorrhage. The CSF spaces are appropriate for the patient's stated age with no midline shift. Normal vascular flow voids are present in the major intracranial vasculature. The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
No significant interval change in the size, number or distribution of numerous punctate nonspecific white matter lesions.
