Ischemic stroke: right sided hemiparesis. There is restricted diffusion in the left hemipons and midbrain with associated high T2 signal. There are mild scattered foci of T2 hyperintensity in the cerebral white matter and other portions of the brainstem. There is no evidence of intracranial hemorrhage or mass. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is a well-defined subcentimeter T2 hyperintense lesion inferior to the right temporomandibular joint. There is partially-imaged periodontal T2 hyperintensity around tooth # 11, which may represent inflammatory changes.
1. Acute infarct in the left pons and midbrain upon a background of probable mild small vessel ischemic disease.2. A well-defined subcentimeter T2 hyperintense lesion inferior to the right temporomandibular joint, which may represent a synovial cyst or parotid cyst, for example, although this is incompletely characterized.Discussed with LUKAS, RIMAS at 9:50 AM on 5/18/15.
