Headache [R51], Reason for Study: ^Reason: monthly headaches for 6 years, now increasing frequency x 2 months associated with blurry vision. Assess for etiology History: monthly headaches for 6 years, now increasing frequency x 2 months associated with No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.There are 2 small developmental venous anomalies, one at the left anterior aspect of supra marginal gyrus (series 1103, image107/200) and another at the left inferior temporal gyrus (series 1103, image 76/200)Several FLAIR/T2 high signal intensity lesions on bilateral subcortical white matter are seen which are non specific.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 mastoid air cells are clear.Retention cyst on the left maxillary sinus.
