Headache [R51], Reason for Study: ^Reason: new onset headaches History: new onset headaches, lightheadedness No evidence of acute ischemic or hemorrhagic lesion on the scan.No evidence of abnormal enhancement.There are multifocal lacunes on bilateral thalami (right worse than left), periventricular white matter and bilateral pons with evidence of susceptibility artifacts indicating possible prior petechial hemorrhages.There are bihemispheric periventricular FLAIR/T2 high signal intensity lesions indicating non specific small vessel ischemic disease.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, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.The sphenoid sinus and frontal sinus especially right side show fluid collections.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No evidence of abnormal enhancement.3. Multiple lacunar infarctions involving bilateral thalami, pons and periventricular white matter with evidence of associated chronic petechial hemorrhages.4. Non specific small vessel ischemic disease.
