unresponsive episodes, known prior infarctions. No evidence of acute ischemic or hemorrhagic lesion.There are lenticular shaped tissue losses on bilateral external capsules, associated with susceptibility artifacts on gradient echo images indicating chronic hemorrhagic lesions.Left basal ganglia and bilateral pons lesions show increased signal intensities on FLAIR images indicating chronic ischemic infarctions.Bilateral centrum semiovale high signal intensities on FLAIR images indicate non specific small vessel ischemic lesions.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or 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. No evidence of acute ischemic or hemorrhagic lesion.2. Likely chronic hemorrhagic lesions on bilateral external capsules and left basal ganglia.3. Likely chronic ischemic lesions on bilateral pontine lesions.4. Non specific small vessel lesions on bilateral centrum semiovale.
