Male, 83 years old, with apraxic gait. A 4 mm focus of restricted diffusion is seen within the left cerebellum. No other areas of diffusion restriction, edema or mass effect are detected. Confluent and patchy periventricular FLAIR hyperintensity is demonstrated. No evidence of acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. A punctate focus of susceptibility along the left lateral ventricular margin may represent chronic microhemorrhage or mineralization. On postcontrast images, no pathologic parenchymal or extra-axial enhancement is observed.
