69 years Male (DOB:1/19/1947)Reason: AMARANTH STUDY SUBJECT - ALZHEIMER'S DISEASE CLINICAL TRIAL History: MEMORY LOSSPROVIDER/ATTENDING NAME: JAMES A. MASTRIANNI JAMES A. MASTRIANNI The temporal horns of the lateral ventricles are relatively large. This was also the case on the prior MR of the brain from 8/7/2014. Biventricular diameter is approximately 42 mm on the current exam and similar dimensions on the prior examNo abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.A T2 hyperintense lesion is redemonstrated in the right lower midbrain.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate mucous retention cyst in the left maxillary sinus and some scattered opacities in the ethmoid air cells. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The eyeball lenses are thin.
1.There is mild ventriculomegaly present which could be related to brain atrophy though could also related to normal pressure hydrocephalus.2.Periventricular and subcortical white matter lesions of a mild degree are nonspecific. At this age they are most likely vascular related. 3.Small lesion in the right midbrain is likely related to old lacunar infarct
