An Acute Case of Exogenous Lipoid Pneumonia Which Developed in Tent Sauna.

The aspiration or inhalation of lipid substances can cause lung injury, including chemical pneumonitis and exogenous lipoid pneumonia. We herein report a case of acute lung injury caused by kerosene inhalation in a tent sauna. A patient developed dyspnea with respiratory failure two hours after igniting a wood-burning stove with kerosene. High-resolution computed tomography revealed widespread ground-glass opacities, and bronchoalveolar lavage revealed lipid-laden macrophages. Systemic corticosteroid treatment led to a rapid improvement. Although kerosene is generally safe at room temperature, its vaporization in high-temperature environments may increase the risk of lung injury through inhalation.
