Migraine No evidence of acute ischemic or hemorrhagic lesion on the scan.There is a small focal high signal intensity on the left precentral gyrus just subcortical white matter over hand motor coordination centimeter (series 1101, image 20/30). This lesion does not show any evidence of restricted diffusion, nor susceptibility artifacts on gradient echo images. Therefore, this likely represent nonspecific in nature.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Non specific single small high signal intensity on FLAIR image on the left precentral gyrus as described above.Otherwise unremarkable brain MRI.
