Description
Flávia Angélica Ferreira Francisco and colleagues describe an 84-year-old man with three years of breathlessness and cough, sometimes productive with clear sputum. Chest imaging showed heterogeneous consolidation in the middle lobe with internal areas of negative attenuation at negative 37 Hounsfield units, a signature of fat. A coronary CT from two years earlier had shown ground-glass opacity at the same site.
The man had used mineral oil for chronic constipation but stopped three years before presentation. History and imaging together pointed to exogenous lipoid pneumonia, in which aspirated lipid triggers lasting inflammation, so no biopsy or lavage was needed. Lipid material apparently kept driving inflammation even after mineral oil use ended, explaining the progression from ground-glass change to consolidation.
