Cerebral aneurysm, nonruptured [I67.1], Reason for Study: ^Reason: annual f/u after diagnosis of basilar aneurysm History: follow up Brain MRINo evidence of acute ischemic or hemorrhagic lesion the scan.A couple of scattered FLAIR/T2 high signal intensity lesions on bilateral cerebellar white matter, these are nonspecific lesions.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. 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. 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 previously identified focal bulge of distal basilar artery indicating possible aneurysm directing anterior and right lateral side is again seen. The luminal diameter of the lesion (about 6mm x 6.5mm) and its configuration do not show any significant interval change since prior scan.Otherwise normal bilateral ICAs, MCAs and ACAs. No other aneurysm is seen.No evidence of intracranial arterial luminal stenosis.
1. Non specific FLAIR/T2 high signal intensity lesions as described above.2. No evidence of acute ischemic or hemorrhagic lesion.3. Unchanged distal basilar artery possible aneurysm size and configuration since prior scan indicating its stability.
