We report 3 patients with (sub)acute onset of dyspnea and orthopnea caused by
bilateral phrenic neuropathy as a neuralgic amyotrophy (NA) subtype. Excruciating
pain, weakness, and atrophy were absent at presentation. All 3 patients were
middle-aged men and had serologic evidence of acute hepatitis E virus (HEV)
infection (IgM and PCR positive). These patients had no history of liver disease or
alcohol abuse. Please see table for patient details.
