Summary
A woman with asthma unresponsive to standard treatments was diagnosed with a subglottic web. This rare condition caused thoracic inlet obstruction, mimicking severe asthma symptoms.
Area of Science:
- Pulmonology
- Otolaryngology
Background:
- Asthma management can be challenging in cases with atypical presentations.
- Refractory asthma necessitates investigation into alternative underlying pathologies.
Observation:
- An atopic woman presented with severe asthma symptoms, including stridor, dysphonia, and dyspnea.
- Her condition did not improve with conventional antiasthmatic therapies, including corticosteroids.
Findings:
- Clinical suspicion of thoracic inlet obstruction was raised due to the constellation of symptoms.
- An esophagogram confirmed the obstruction, and direct laryngoscopy revealed a subglottic web.
Implications:
- Subglottic webs are a rare but critical differential diagnosis in refractory asthma.
- Accurate diagnosis requires a high index of suspicion and appropriate diagnostic imaging and visualization.
