Overview
Common chest x-ray findings in chronic PCM include bilateral and symmetric opacities, butterfly wing pattern, architectural distorsion, paracicatricial emphysema and traction bronchiectasis. There are not many chest x-ray finding in acute PCM, but it is characterized by mediastinal and hiliar lymphadenopathy and pleural effusions.[1] On thoraxic CT scan, chronic paracoccidioidomycosis is characterized by ground-glass attenuation, airspace consolidations, interlobular septal thickening, nodular pattern, fibrotic pattern, cavitary lesions, halo sign and reversed halo sign.[2][3][4][1]
Chest X-ray
- Chronic PMC:
- Bilateral and symmetric opacities

- Pleural effusions[1]
Computed Tomography
- Ground-glass attenuation
- Airspace consolidations
- Interlobular septal thickening
- Nodular pattern:
- Miliary
- Macronodular
- Fibrotic pattern:
- Peribronchovascular interstitial thickening
- Areas of cicatricial emphysema
- Traction bronchiectasis
