case_images: Brain computed tomography (CT) imaging of an 88-year-old woman with non-ketotic hyperglycemia chorea-ballism and intracerebral hemorrhage. (A,B) At admission, CT showed hyperdense lesions in the left occipital lobe (white arrow), right caudate nucleus and putamen (triangle), and left caudate (triangle). (C,D) Eight hours later after admission, CT showed mild hematoma enlargement, slightly increased edema around the occipital lobe lesion (white arrow), and no significant changes in the bilateral striatum regions (triangle); (E,F) 15 days before admission, CT showed hyperdensity in bilateral striatum regions (triangle) without edema and occipital lobe lesion.

case_images: A non-contrast brain computed tomography (CT) showed hyperdensity in the left occipital lobe with a mean CT attenuation value of 72 Hounsfield unit (HU) and bilateral striatal regions (right caudate nucleus and putamen with a mean value of 49 HU, left caudate nucleus with a mean value of 43 HU) (Figures 1A,B). A contrasted brain CT at 8 h later of hospitalization, however, disclosed the over-time evolution differences in these lesions: slightly increased edema around the occipital lobe lesion with mild hematoma enlargement (a mean value of 75 HU), whereas no significant changes in the striatal regions were observed (still regular, well-defined, limited without edema, and mass effect; a mean value of 51 HU and 44 HU in the right and left side, respectively), reassuring that the striatum lesions were not hemorrhagic damage (Figures 1C,D). A chart review of her 15-day-ago records with a CT image of hyperdensity in bilateral striatum (a mean value of 46 HU and 43 HU in the right and left side, respectively) without edema, mass effect, and occipital lobe lesion (Figures 1E,F) further confirmed our diagnosis.
