There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Previously shown left pontine lesion is not shown on this scan. It was not demonstrated on immediate prior scan either.2. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancing lesion.3. No change of right basal ganglia DVA.
