headache, left side. No evidence of acute ischemic or hemorrhagic lesion on this scan.Scattered foci of high signal intensities on FLAIR images are again demonstrated, no change since prior exam.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. 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.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal bilateral ICAs, MCAs and ACAs. The left PCA is fetal origin and the vertebrobasilar system appears to be normal.There is no evidence of intracranial arterial aneurysm or stenosis.
No evidence of acute ischemic or hemorrhagic lesion on this scan.No interval change of minimal small vessel disease since prior exam.Normal brain MRA.
