Cerebral aneurysm, nonruptured [I67.1] / Migraine without aura, intractable, without status migrainosus [G43.019], Reason for Study: ^Reason: daily HA question of ACOM aneurysm History: Daily HA Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement. 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.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate about 2.2mm x 1.5mm sized posteriorly and slightly right laterally direction luminal bulge arising from the left ACA A1-A2 junction which likely represent an anterior communicating artery aneurysm.No other aneurysm is seen.Vertebrobasilar system appears to be normal.
1. No evidence of acute ischemic or hemorrhagic lesion.2. About 2mm x 1.5mm sized left side Acom aneurysm. Comment: head CT angiography can be considered for more precise anatomical evaluation of the aneurysm.
