Highlights
- Hyperglycemic hemichorea is associated with characteristic striatal MRI and CT abnormalities.
- The affected striatum is usually hyperintense on T1-weighted MRI and hyperdense on CT.
- Hyperintensity on T1-weighted MRI is likely associated with increased blood flow and extravasation.
- Isolated hyperdensity on CT might be consistent with vasodilation and increased blood flow preceding extravasation.
