83-year-old woman with headache. Question intracranial hemorrhage. There is no evidence of intracranial hemorrhage, mass or edema. Right frontal encephalomalacia remains. Extensive periventricular and subcortical white matter hypoattenuation is present. This most likely represents age-indeterminate small vessel ischemic disease. Large vessel calcifications are noted. If acute stroke is suspected, MRI is recommended. The ventricles and basal cisterns are unchanged in size and configuration from the CT scan dated 10/20/2009.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized. Calcifications of the lateral limbus of the right eye are unchanged.
