 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 no pathological enhancement. There is redemonstration of foci of ill-defined enhancement within the central pons with a smaller focus in the right paramedian pons just cranially. These correspond to areas of abnormality seen at the edge of the field of view on MRI of the cervical spine. These demonstrate associated ill-defined susceptibility. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is a small mucosal retention cyst in the right maxillary sinus. Minimal mucosal thickening is noted in the left anterior ethmoid air cells. There is under pneumatization of the mastoids bilaterally.
1.Ill-defined small areas of enhancement in the central pons with associated mild susceptibility consistent with incidental capillary telangiectasias. No MR evidence of intracranial metastatic disease.2.Other scattered nonspecific punctate foci of T2/FLAIR hyperintensity within the subcortical and periventricular white matter without enhancement, which are nonspecific. Differential diagnosis would include infectious/inflammatory etiologies, chronic small vessel ischemic changes, demyelinating disease, and migraine headaches. Please correlate clinically.
