sudden onset right arm and leg weakness, dysphagia There is focal restricted diffusion on the left internal capsule posterior limb without evidence of hemorrhagic lesion. This lesion indicates acute ischemic infarction.Underlying brain shows periventricular white matter high signal intensities on FLAIR images indicating non specific small vessel disease.The ventricles, sulci and cisterns are symmetric and unremarkable. 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. Acute ischemic infarction on the left internal capsule posterior limb without evidence of hemorrhagic conversion.2. Otherwise no remarkable finding.
