Resumo: Acute sensory ataxic neuropathy (ASAN) is known to occur with acute and monophasic sensory ataxia. Although autonomic dysfunctions have been reported, no detailed descriptions are currently available. We describe a case of ASAN in which the autonomic manifestations were systematically investigated. Although the patient did not complain of any autonomic symptoms, except for photophobia due to mydriasis, autonomic testing revealed widespread autonomic dysfunctions. Norepinephrine and dobutamine infusion test indicated the presence of sympathetic dysfunction. Additionally, the pupillary response to pilocarpine revealed the presence of parasympathetic dysfunction. In conclusion, widespread, subclinical autonomic dysfunctions may be present in ASAN patients.
