80-year-old male with gait and imbalance. Patient with parkinsonism, predominantly lower body; history of HLD; evaluate for vascular parkinsonism vs. NPH There is an area of hemosiderin stained encephalomalacia within the left inferior frontal lobe as well as additional scattered foci of hemosiderin deposition elsewhere, predominantly within the left frontal lobe. No acute intracranial hemorrhage or parenchymal edema is identified. No abnormal mass lesions are appreciated intracranially. No restricted diffusion is noted to suggest acute ischemia. The CSF spaces are appropriate for the patient's stated age with no evidence of significant deviation or mass effect. Vascular flow voids are intact with no definite evidence of vascular disease.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1. Hemosiderin staining encephalomalacia within the left inferior frontal lobe as well as additional scattered foci of hemosiderin deposition elsewhere predominantly within the left frontal lobe. Findings could represent sequela of remote traumatic injury. 2. No acute intracranial hemorrhage or ischemia is noted.
