45-year-old woman status post repair of type B aortic dissection now with increased ICP and headache. The quality of the study is suboptimal. Since the previous study, diffuse effacement of the cortical sulci has developed. There is interval decrease in size ventricular system and partial effacement of the basal cisterns. These findings are consistent with diffuse cerebral edema. There is hypoattenuation in the right MCA territory suggestive of cortical edema. Recommend MRI to assess for acute stroke.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized. Incidental note is made of an accessory suture in the frontal bone.A nasogastric tube is present in the right naris.
1. Interval development of diffuse cerebral edema.2. Cortical hypoattenuation in right MCA territory. Recommend MRI to evaluate for acute stroke.
