59-year-old female with history of left-sided weakness. There is a 10 x 7-mm focus restricted diffusion with associated increased T2 signal abnormality within the left aspect of the pontomedullary junction compatible with an acute ischemic infarct. Additionally, there is moderately increased T2/FLAIR signal abnormality within the periventricular and subcortical white matter. No midline shift or mass-effect. There is no evidence of intracranial hemorrhage. The basal cisterns are intact. The ventricles and sulci are symmetric. Flow-voids are appreciated in the major intracranial vessels. The imaged orbits, paranasal sinuses and mastoid air cells are clear.
1. Small acute ischemic infarction within the left aspect of the pontomedullary junction.2. Moderate chronic small vessel ischemic disease.
