Flow-volume curve was almost overlapped before and after inhalation of beta2-stimulant. It revealed no reversibility after inhalation. Although both %VC and FEV 1% were within normal limit, the flow-volume curve was convex downward and the level of V50/V25 was increased.

Lung function tests showed no reversibility of FEV1 by the beta-adrenergic agonist salbutamol, but V50/V25 in flow-volume curve was elevated to 4.55, suggesting the existence of peripheral airway obstruction (Fig. 1).
Infiltrative shadow which suggests pneumonia in right lower lobe (A). Centrilobular nodular shadow in left upper lobe with slight to moderate bronchial wall thickening and bronchiectasis (B). Splenomegaly (C).

In chest CT taken on admission, infiltrative shadow in right lower lobe and centrilobular nodular shadow in left upper lobe accompanied by bronchial wall thickening and bronchiectasis were noted (Fig. 2A, B). Splenomegaly was also observed (Fig. 2C).
