Progressive Supranuclear Palsy (PSP)
- 75-year-old patient with postural instability and supranuclear palsy.
- The midbrain tegmentum is atrophic causing a flattened superior border.
- The DaTscan shows reduced tracer uptake in the putamina (particularly on the right).
- 65-year-old patient presented with instability, free falls, and a vertigcal gaze palsy.
- MRI showed marked atrophy of the pons.
- DaTscan showed loss of normal tracer uptake in both corpora striata.
- 60-year-old patient presented with poor balance, multiple falls, and rigidity. Initially diagnosed with Parksinson's disease, there was a poor response to levdopa.
- MRI showed marked midbrian atrophy (as well as a moderate burden of small vessel disease).
- 70-year-old patient presented with parkinsonism.
- MRI showed marked atrophy of the midbrain over a three year period.
- DaTscan showed high background uptake and with loss of the normal updake in the striatum.
