Vocal cord dysfunction (VCD) mimics asthma symptoms, leading to misdiagnosis. Early VCD diagnosis and treatment, including psychotherapy, resolve symptoms and avoid aggressive interventions.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Psychiatry

Background:

  • Vocal cord dysfunction (VCD) is characterized by paradoxical vocal cord adduction during respiration.
  • Symptoms like wheezing and dyspnea often mimic asthma, leading to misdiagnosis and inappropriate treatment.

Observation:

  • An 11-year-old girl with intractable dyspnea, unresponsive to asthma medications, presented with abnormal flow-volume loops.
  • Diagnostic imaging (CT, MRI) revealed no structural abnormalities, but fibroscopy showed paradoxical vocal cord adduction.

Findings:

  • Vocal cord dysfunction was diagnosed, and symptoms resolved with psychiatric treatment and speech therapy.
  • Repeat fibroscopy confirmed the absence of adduction post-treatment, validating the VCD diagnosis.

Implications:

  • VCD can be mistaken for or coexist with asthma, necessitating a high index of suspicion in non-responsive wheezing cases.
  • Early diagnosis of VCD prevents unnecessary aggressive medical or surgical interventions.
  • Treatment focuses on respiratory exercises, voice therapy, and psychotherapy for effective symptom management.
