case_images: Five months after the acute event, a chest HRCT revealed biapical subpleural parenchymatous condensations; 10*25 mm in the right upper lobe ( Figure 1) and 18*11 mm in the left upper lobe ( Figure 2).

case_images: A scan-guided trans-parietal lung biopsy showed lung parenchyma tattooed with anthracotic deposits, largely remodeled by fibrous tissue, intermingled with numerous wavy and refractive dyselastotic structures in polarized light ( Figure 3).
case_images: The orcein staining confirms the presence of excess elastotic fibers within these lesions.
