New daily persistent headache [339.42], Reason for Study: ^Reason: brain lesion or dural enhancement? History: daily headaches No evidence of acute ischemic or hemorrhagic lesion.There is no abnormal enhancement.There are scattered multiple high signal intensities on FLAIR imaging on bilateral hemisphere subcortical white matter (series 801, image 18, 19 and 22) , which most likely to be nonspecific.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.
Nonspecific white matter high signal intensity lesions as described above.Otherwise no evidence of acute ischemic or hemorrhagic lesion, no abnormal enhancement.
