See the list below:

  • Brain MRI may be useful, particularly in cases of centrally mediated dysautonomia.

  • In MSA, brainstem or cerebellar atrophy may be seen, with T2 hyperintensity of the pons (the hot-crossed bun sign); these findings differentiate MSA from the other conditions of primary autonomic dysfunction. [4]

  • No imaging abnormalities are expected in pure autonomic failure, autoimmune autonomic neuropathy, or postural orthostatic tachycardia syndrome.
