 Numerous FLAIR hyperintense foci are seen in the subcortical and periventricular white matter. Similar foci are seen in the centrum semiovale bilaterally, in the midbrain, pons and medulla. These foci are nonspecific but likely relate to chronic ischemic microvascular disease.Apparent punctate enhancement is suggested in the right aspect of the medulla (1501/32) and in the right aspect of the pons with no definite enhancement on the earlier obtained fat saturation post-contrast images. There is no corresponding abnormalities on T2 images, and therefore these are felt to be artifactual.Ventricular size is normal with no evidence of midline shift. No acute hemorrhage or edema. There are no diffusion abnormalities.There is a prominent area of intrinsic T1 hyperintensity in the suprasellar region posteriorly without significant superimposed enhancement and without drop out of signal on fat saturated images, consistent with an incidental ectopic posterior pituitary gland.There is leftward deviation of the nasal septum. There are mucous retention cysts in the posterior nasopharyngeal soft tissue. Scattered mucosal thickening is seen in the paranasal sinuses.
1. No definite evidence of metastatic brain disease. 2. Incidental ectopic posterior pituitary.3. Moderate chronic small vessel ischemic changes.
