Table 1. Severity of pulmonary involvement in paracoccidioidomycosis patients on chest radiograph. Evaluation of active disease and residual form.

Severity	Active disease	Residual form
Mild	One or two focal lesions* in the same third or not; or pure alveolar lesions of any size. Other possible findings: nodules.	Discrete fibrotic lesions, mainly parenchymal bands in middle pulmonary third. Normal chest radiograph: rare.
Moderate	≥ 3 focal lesions or interstitial or mixed lesions involving < ⅓ of the total pulmonary parenchyma. Other possible findings: Nodules, bronchial wall thickening (tram-track sign).	Fibrotic lesions: - parenchymal bands; - coarse nodules; - wall thickened bronchi; - thin-walled cavities.
Severe	Interstitial or mixed lesions involving > ⅓ of the total pulmonary parenchyma area. Other possible findings: nodules, bronchial wall thickening, bronchiectasis, cavitary lesions.	Fibrotic lesions: - parenchymal bands, and/or - coarse nodules, and/or - wall thickened bronchi, and/or - ≤ 2 mm thin-walled cavities; plus At least three of the signs of pulmonary hyperinflation below: - low and flattened diaphragm; - increased retrosternal airspace; - hyperlucent areas; - bullae.

*The authors use the expression focal lesions for alveolar opacities in consolidation or ground-glass opacities, nodules, or masses.
