Altered mental status [780.97], Reason for Study: ^Reason: 73 y/o M with metastatic colon ca, altered mental status, r/o brain metastasis History: altered mental status There is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement.Mild diffuse brain atrophy with appropriate ventricular system size.Multifocal patchy bihemispheric periventricular white matter indicate non specific small vessel ischemic disease.On gradient echo images, there are multiple variable sized susceptibility lesions on bilateral hemispheres without evidence of surrounding edema or restricted diffusion. These lesions may indicate chronic petechial hemorrhagic foci or calcifications. The midline structures and cranial-cervical junction are normal. Intracranial arterial system appears to be tortuous in course and slightly ectatic indicating atherosclerotic changes.The paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Diffuse mild brain atrophy with non specific small vessel ischemic changes.3. No evidence of abnormal enhancement.
