Hemangioma of intracranial structures [D18.02] / Headache [R51] / Cerebral aneurysm, nonruptured [I67.1], Reason for Study: ^Reason: yearly surveillance of ccm/aneurysm History: headaches Brain MRINo evidence of acute ischemic or hemorrhagic lesion.Multifocal various sized susceptibility lesions throughout the brain including pons, midbrain, right frontal and left occipital lobes are again seen, unchanged.No evidence of associated surrounding edema indicating recent hemorrhages.No evidence of abnormal enhancement either.The ventricles, sulci and cisterns are symmetric and unremarkable. 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 2mm sized right ACA proximal A2 segment. The size and configuration of the aneurysm appear to be stable since prior scan.Bilateral Pcom arteries and Acom artery are patent.There is no other intracranial arterial aneurysm seen.There is no evidence of intracranial arterial luminal stenosis.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No change of multiple susceptibility lesions in the brain.3. No change of 2mm sized right ACA A2 segment aneurysm since prior scan.
