[...]. Acute hypersensitivity pneumonitis. CTICases. Published November 1, 2018. https://str-case-explorer.pages.dev/c/hzzex
Imaging findings
Chest CT shows diffuse, bilateral ground-glass opacities in the lower lobes with geographic areas of lung sparing, and numerous centrilobular nodules in the upper lobes, in a patient with acute dyspnea after bird exposure. Biopsy confirmed non-necrotizing granulomas.
Key takeaways
Acute hypersensitivity pneumonitis can present as an acute lung injury with extensive ground-glass opacities and centrilobular nodules following massive antigen inhalation (such as bird droppings). It must be differentiated from diffuse alveolar damage.
