New daily persistent headache (ndph) [G44.52], Reason for Study: ^Reason: evaluate for mass History: new onset headache in older patient There is no evidence of acute ischemic or hemorrhagic lesion. There is no evidence of abnormal enhancement.Scattered FLAIR/T2 high signal intensity lesions are seen on bilateral subcortical white matter which are nonspecific.The ventricles, sulci and cisterns are 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.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No evidence of abnormal enhancement.3. Nonspecific subcortical white matter FLAIR/T2 high signal intensity lesions. Differential diagnosis include nonspecific small vessel ischemic disease. Other white matter diseases such as demyelinating disease is less likely. Clinical correlation is recommended.
