63-year-old male with altered mental status, assess for etiology. CVA, hemorrhage, mass.IMAGE ACQUISITION: Nonenhanced CT of the head. No acute intracranial abnormality is evident. Specifically, there is no evidence of intracranial hemorrhage, focal mass, edema, midline shift, or hydrocephalus. There is no CT evidence for acute territorial ischemia.Again demonstrated is extensive hypoattenuation in the supratentorial white matter, unchanged and most consistent with small vessel ischemic disease. Atherosclerotic vertebral and internal carotid arteries arteries are again noted.Persistent opacification of the bilateral mastoid air cells with soft tissue attenuation within the left external auditory canal, unchanged. Please refer to recent MRI of the internal auditory canal for additional details.
