Altered mental status [780.97], Reason for Study: ^Reason: PT with recent bacteremia now altered mental status. Concern for CNS infection. History: PT with recent bacteremia now altered mental status. Concern for CNS infection. Motion artifacts degraded exam quality.There are restricted diffusion areas including on the left caudate nucleus head and bilateral internal capsule as well as right thalamus mesial aspect indicating acute ischemic infarct.There is no evidence of acute hemorrhagic lesion on the scan.Focal susceptibility artifacts on the left frontal lobe, no change since prior exam. Underlying brain shows minimal to mild diffuse brain atrophy which is age appropriate.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear. There is opacification on the left mastoid air cell.
Acute ischemic infarcts without hemorrhagic transformation on bilateral internal capsule, left caudate nucleus and right thalamus mesial aspect as described above.
