 Examination is mildly limited secondary to patient motion. The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. Multifocal small round subcortical T2 hyperintense foci are noted without associated susceptibility artifact or enhancement. Additionally, there is patchy T2 hyperintensity within the pons. There are no areas of pathological enhancement. 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 fluid in the bilateral mastoid air cells, left greater than right. Patchy T1 and T2 signal hyperintensity in the left posterior tongue with suggestion of volume loss may represent posttreatment/postoperative changes when compared to prior MRI of the neck dated 05/18/2016.
1.No areas of abnormal pathologic enhancement to suggest metastatic disease.2.Multiple foci of subcortical T2 hyperintensity are nonspecific, some of which may represent mild chronic small vessel ischemic changes, with smaller foci along the superior frontal gyri possibly relating to enlarged perivascular spaces with marginal gliosis.3.Postoperative/posttreatment changes suggested along the left posterior oral tongue, incompletely evaluated
