The most frequent high‐resolution computed tomography (HRCT) features (increased lung volume, inspiratory decreased attenuation, mosaic pattern, and expiratory air trapping) showed significantly greater scores in OB patients. Patients with PSA have shown a higher frequency of atopy (<jats:italic>P</jats:italic> &lt; 0.05). ROC curve analysis demonstrated discriminative power for the LF variables, HRCT findings and for atopy between diagnoses. Further analysis released five final variables more accurate for the identification of a third diagnostic group (FVC%t, post‐bronchodilator ΔFEV<jats:sub>1</jats:sub> in ml, HRCT mosaic pattern, SPT, and <jats:italic>D. pteronyssinus</jats:italic>‐specific IgE).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>We found that OB and PSA possess identifiable characteristic features but overlapping values may turn them undistinguishable.
