2 year-old female with history of sickle cell disease and status post Moya Moya surgery. Evaluate for hematoma and CVA. Examination demonstrates an area of hypoattenuation in the right superior frontal gyrus, which corresponds to that on MRI 1/21/2010 and is compatible with a subacute stroke. There is no appreciable change in CT attenuation of areas of the acute infarcts involving bilateral centrum semiovale and right posterior parietal lobe previously seen on MRI. New since prior exam is a focus of hyperattenuation along the left postcentral gyrus, compatible with cortical hemorrhage. New since prior exam are postsurgical changes status post bilateral temporal craniotomies. There are small amount of blood products in the left temporal extraaxial space under the cranial flap. There is bilateral temporal scalp soft tissue swelling. There are small amount of pneumocephalus in the bifrontal regions and in the interhemispheric fissure and small emphysema in the left frontal subgaleal region. There are 2 Burr holes in the bifrontal bones. The ventricles, sulci, and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass effect, or midline shift. The osseous structures are unremarkable except for postsurgical changes. The mastoid air cells are clear. There is opacification of the ethmoid air cells.
1. New focus of cortical hemorrhage at the left postcentral gyrus. 2. Interval postsurgical changes status post bilateral temporal craniotomies as described above. 3. Right superior frontal subacute stroke.
