Headache [R51], Reason for Study: ^Reason: new type of headache History: new headache No evidence of acute ischemic or hemorrhagic lesion.Multiple scattered bihemispheric high signal intensities on FLAIR/T2 images on periventricular white matter and centrum semiovale indicating nonspecific 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 paranasal sinuses and mastoid air cells are clear.
Minimal nonspecific small vessel ischemic disease.No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.
