There are multiple abnormal areas of low attenuation within both hemispheres which are irregular, some quite confluent, which appear to preferentially affect the white matter. These lesions do not appreciably enhance post-contrast. The sulci, basal cisterns and ventricles appear normal. No bulging of the fontanelles. No shift of midline structures or brain herniation. Normal venous sinuses. No acute intracranial haemorrhage or extra-axial collection. Normal appearance of the mastoid air spaces. No destructive bone lesion.
