Vocal cord dysfunction (VCD) mimics asthma but is a functional disorder. Early recognition and direct visualization are key to avoiding misdiagnosis and unnecessary corticosteroid treatment for patients.

Area of Science:

  • Pulmonology
  • Otolaryngology

Background:

  • Vocal cord dysfunction (VCD) is an uncommon condition where vocal cords adduct abnormally.
  • It can be mistaken for or occur alongside bronchial asthma, leading to misdiagnosis.

Observation:

  • Patients with VCD may not respond to bronchodilators.
  • Spirometry may show poor reproducibility and inspiratory loop truncation.
  • Direct visualization of vocal cords during an episode is diagnostic.

Findings:

  • Misdiagnosis of VCD as severe or refractory asthma can lead to high-dose corticosteroid use.
  • Unnecessary steroid treatment can result in significant toxicity.

Implications:

  • Increased clinical suspicion for VCD is crucial in patients with asthma-like symptoms unresponsive to treatment.
