53-year-old male with a history of small enhancement in the pons on the previous MRI Brain. Evaluate for interval change. Brain CCM:The ventricles and sulci are prominent, consistent with mild age-related volume loss. The basal cisterns remain patent. There is no midline shift or mass effect. There are multiple nonspecific scattered punctate foci of abnormal T2/FLAIR hyperintensity within the periventricular and subcortical white matter. There is redemonstration of foci of ill-defined enhancement within the central pons with a smaller focus in the right paramedian pons just cranially which is unchanged. These demonstrate stable ill-defined susceptibility. There is no diffusion abnormality. No extra-axial fluid collection is identified. The midline structures and craniocervical junction are within normal limits. There is a small mucosal retention cyst in the right maxillary sinus. Brain MRA:There is no detectable vascularity within the pons. There is an incidental finding of a 2 x 3 mm outpouching off of the left supraclinoid ICA projecting inferiorly compatible with a small aneurysm. The intracranial internal carotid arteries are otherwise normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis.
1.Stable likely incidental capillary telangiectasias in the central pons.2.Scattered unchanged nonspecific punctate foci of T2/FLAIR hyperintensity within the subcortical and periventricular white matter.3.Incidental 2 x 3 mm inferiorly directed left supraclinoid ICA aneurysm.
