Headache, dizziness, blurred vision, evaluate for posterior circulatory insufficiency. MRI Brain:No restricted diffusion to suggest acute infarction. No evidence of acute intracranial hemorrhage or extraaxial collection. A 12 mm dural based lesion along the left convexity is incompletely characterized without contrast but is without associated mass effect. There are a few scattered punctate foci of white matter T2 hyperintensity, which are nonspecific but most consistent with mild chronic small vessel ischemic disease. Otherwise, the signal intensity of the brain parenchyma is within normal limits. No midline shift or herniation. Note is made of an empty sella, a normal variant. The ventricles and sulci are normal in size. There is a mucus retention cyst in the right maxillary sinus. Remainder of the calvarium and extracranial soft tissues are grossly unremarkable.MRA Brain:MR angiographic demonstrate the anterior and posterior intracranial arterial circulations to be patent without evidence of flow limiting stenoses or aneurysm.
1. No evidence of acute infarct, hemorrhage, or intracranial mass effect. Mild chronic small vessel ischemic changes.2. Small dural based lesion along the left frontal convexity with calcification is favored to represent a small meningioma but is not well characterized without contrast. No associated mass effect. 3. No significant stenosis in the intracranial circulation.
