Had an MRI with and without contrast: The reason for MRi were occassional electrical sensation in the L temporal area which lasted 10-30 sec. Also the occassional smell of smoke not related to the electrical sensation. I am a healthy 57 year old female who does not take any prescribed medication except for a Femring for Menopausal symtoms. The findings were There are a few small nonspecific foci of prolonged T2 signal in the periventricular white matter bilaterally more evident in the left hemisphere, left frontal and parietal lobes. No evidence of a mass lesion, acute parenchymal hemorrhage or acute infarction; No evidence of a posterior or fossa mass or mass involving either IAC or CPA cistern. Mild Muscosal thickening posteriorly in the left maxillary sinus . (Had a sinus infection about 2 weeks ago) Conclusion: 1). Nonspecfic mild number of foci of prolonged T2 signal in the periventricular white matter. Considerations include gliosis along with less likely acute serration, demyelination, infection or vasculitis. 2). No evidence of mass lesion or acute infarction. What does this mean?
