AI Article Synopsis
- A 73-year-old man with a persistent cough underwent chest CT scans, revealing lung abnormalities and elevated blood markers for inflammation.
- After conducting an antigen avoidance test, both his lung imaging and blood results showed improvement, leading to a diagnosis of hypersensitivity pneumonitis (HP).
- The source of his HP was traced to mold found on decaying walls in his home, highlighting the need for a systematic approach to identify the triggers of this condition.
Article Abstract
A 73-year-old man visited our hospital for persistent cough. Chest high-resolution CT (HRCT) showed infiltration shadows in lower lobes and diffuse ground glass opacities in the upper lobes. Blood tests showed elevated white blood cell, C-reactive protein, surfactant protein D, and Krebs von den Lungen-6 levels. After an antigen avoidance test, his HRCT and blood test findings improved; we diagnosed him with hypersensitivity pneumonitis (HP). A culture of the rotting interior walls within his home revealed , which we believe caused his HP. Given the few patients with induced HP, systematic approach was important to identify the inciting antigen.
