Difficult to treat asthma - The importance of thoracic imaging

Asthma is a chronic disease with clinical variations throughout its course. Periods of symptom aggravation can occur with the need to escalate therapy. Nevertheless, further investigation should be considered when atypical manifestations appear or when worsening of symptoms occurs. Proximal tracheal/bronchial obstruction can mimic symptoms observed in patients with asthma. Primary benign tracheal tumors are rare, but can constitute the cause for such symptoms. We present a case report of a patient with asthma and a tracheal lesion.
