Migraine with aura There is a focal relatively well-circumscribed about 5 mm sized high signal intensity lesion on FLAIR and T2 weighted image on the right hippocampal gyrus. The lesion is not enhancing and does not show any evidence of local mass effect or surrounding edema. Comparing to prior scan, considering the difference of imaging acquisition technique, there is no significant interval change in terms of size, and MR characteristics.There is no evidence of acute ischemic or hemorrhagic lesion. There is no evidence of abnormal enhancement.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. 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.
No interval change of right hippocampal gyrus high signal intensity lesion on FLAIR in terms of size and MR characteristics since prior scan.No evidence of acute ischemic or hemorrhagic lesion.
