Absent cough and gag reflexes. Evaluate for encephalopathy. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is diffusely diminished white matter volume. There is diffuse thinning of the corpus collusum. Myelination appears within normal limits for age. There is mild prominence of the extraaxial CSF spaces which can be a normal variant in this age group. There is a cavum vergae. No hydrocephalus. There is no midline shift or herniation. There is mild asymmetric flattening of the left parieto-occipital calvarium, which may be related to positional plagiocephaly. The skull and extracranial soft tissues are otherwise unremarkable.
1. No evidence of acute ischemia, mass or mass effect. No abnormal enhancement.2. Diffusely diminished supratentorial white matter volume with associated thinning of the corpus callosum.
