Multisystem Atrophy - Parkinsonian Type (MSA-P)
- 55-year-old female with left sided parkinsonism and orthostatic systoms.
- 80-year-old patient presented with asymmetric parkinsonism (left > right) with freezing and early falls with poor response to levodopa.
- MRI showed putaminal atrophy, susceptibility artefact and T2-hyperintensity along the lateral aspect of the putamina.
- DaTscan showed markedly reduced tracer uptake in the putamina bilaterally.
- 60-year-old patient with a bilateral tremor.
- T2 weighted imaging shows the lateral rim sign and mild putaminal volume loss.
- While SWI was not performed, low signal was seen in the putamina on EPI DWI, which is sensitive to susceptibility artefact.
