Neurology: Case of the Month

Test Yourself — Patient 22

Multi-System Atrophy (MSA)

  1. All of the following are considered to be one of the multi-system atrophies EXCEPT:
    • [ A ] Progressive Supranuclear Palsy (PSP)
    • [ B ] Striatonigral degeneration
    • [ C ] Olivopontocerebellar atrophy
    • [ D ] Shy-Drager syndrome
  2. The multi-system atrophies are most strongly associated with which of the following pathological inclusion bodies?
    • [ A ] An intracytoplasmic, eosinophilic neuronal inclusion with a surrounding halo
    • [ B ] An intracytoplasmic, eosinophilic oligodendroglial inclusion
    • [ C ] An intranuclear, eosinophilic neuronal inclusion
    • [ D ] An argyrophilic, intracytoplasmic neuronal inclusion
    • [ E ] An argyrophilic, intranuclear neuronal inclusion
  3. All of the following are true statements regarding the multi-system atrophies EXCEPT:
    • [ A ] In Shy-Drager syndrome, the predominant features are parkinsonism and dysautonamia.
    • [ B ] In patients with parkinsonism, dysautonomia is diagnostic of Shy-Drager syndrome.
    • [ C ] Patients with OPCA may demonstrate gaze impairment, pyramidal dysfunction, and axial rigidity.
    • [ D ] Striatonigral degeneration is occasionally associated with cervical dystonias.
    • [ E ] Pyramidal signs are fairly common in patients with multi-system atrophy.
  4. All of the following signs/symptoms may be found in patients with one of the multi-system atophies EXCEPT:
    • [ A ] Rigidity
    • [ B ] Autonomic dysfunction
    • [ C ] Ataxia
    • [ D ] Hoffman's sign
    • [ E ] Alien limb phenomenon
  5. All of the following statements are TRUE regarding the multi-system atrophies EXCEPT:
    • [ A ] Patients with these conditions tend to respond poorly to DOPA replacement, in part, because the defect lies in loss of the dopamine receptor.
    • [ B ] Parkinsonism is found in most, if not all, cases of multi-system atrophy.
    • [ C ] Autonomic symptoms occur commonly in patients with MSA.
    • [ D ] Lewy bodies are the pathologic hallmark of this disease.
    • [ E ] Most cases of MSA present in a symmetrical fashion in contradistinction to Cortico-basal ganglionic degeneration.
