Chest X-rays and computed tomography (CT) showed no significant alterations, except right basal segmental atelectasis and adenopathies of a reactive appearance ( fig. 1 ). Considering the persistent cough despite optimum treatment, bronchoscopy was decided upon, the findings being suggestive of inflammatory thickening of the dividing carinal region of the segmental bronchi of the right upper lobe (RUL; fig. 2 ).
