Migraine without aura, intractable, without status migrainosus [G43.019] / Obesity, unspecified [E66.9], Reason for Study: ^Reason: 46 y.o,. with worsening headaches c/w migraine but hx of cancer - tumor, other mass lesion? History: worsening headache, Brain MRINo evidence of acute ischemic or hemorrhagic lesion.Right parieto-temporal lobe high signal focus on FLAIR images is non specific.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. A small left maxillary sinus retention cyst.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. Bilateral PCAs are fetal origin.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Normal brain MRA.
