Clinical question: Rule out intracranial hemorrhage, abscess, mass. Signs and symptoms going altered mental status, short-term memory loss. Non-infused head CT:The examination again demonstrates extensive subcortical and periventricular diffuse areas of low-attenuation with no appreciable interval change since prior MRI examination of 3 -- 29 -- 11. Findings likely represent post therapy changes. A shunted right lateral ventricle with no change in the size of ventricular system since prior study. Prominence of cortical sulci for patient's stated age concerning for underlying parenchymal volume loss.No evidence of hemorrhage, edema, mass effect or midline shift. No hydrocephalus.
1.Shunt in the right lateral ventricle and stable ventricular system since prior exam.2.Post therapy changes of bihemispheric white matter.3.No detectable acute intracranial findings.4.Extensive opacification of paranasal sinuses with fluid levels within bilateral maxillary sinuses.
