Seizure. There are large areas of restricted diffusion and high T2 signal in the bilateral frontal lobes, bilateral cingulate gyri, and left temporal, parietal, and occipital lobes. There are high T1 and T2 signal subdural fluid collections along the bilateral occipital convexities that measures up to 2 mm in thickness. In addition, there is diffuse restricted diffusion in the corpus callosum and along the posterior limbs of the bilateral internal capsules, with extension into the midbrain on the left. There is otherwise a background of normal myelination. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and paranasal sinuses are grossly unremarkable. However, there is an apical subgaleal fluid collection that measures up to 9 mm in thickness.
1. Recent infarcts involving the bilateral cerebral hemispheres, left more than right.2. Early subacute subdural hemorrhage along the bilateral occipital convexities that measures up to 2 mm in thickness. Discussed with nurse practitioner Sherri Sadler at 1:45 PM on 7/20/15.
