Chest computed tomography scan obtained 5 months before presentation.. Note: Reticular shadows can be observed in the periphery of both lungs.

At that time, computed tomography (CT) showed ground glass opacities and peripheral reticular opacities (Figure 1), while bronchoscopy revealed a 20% increase in eosinophils in his bronchoalveolar fluid.
Chest computed tomography (CT) scan obtained on presentation to our institute.. Notes: Subcutaneous fat has decreased because of weight loss. The mediastinal fat observed on CT performed 5 months ago has been replaced by gas density (white arrow).

Chest CT performed at the current examination showed a rapid decrease in mediastinal fat when compared with the scan obtained 5 months back, with the space created by the diminished fat replaced by gas density (Figure 2).
Chest computed tomography scan obtained at the 10-month follow-up visit.. Note: An increase in subcutaneous and mediastinal fat is accompanied by disappearance of the gas density in the mediastinum.

A routine follow-up CT performed 10 months after discharge showed some increase in subcutaneous mediastinal fat and disappearance of the gas density in mediastinum (Figure 3).
