An Acute Case of Exogenous Lipoid Pneumonia which Developed in Tent Sauna: A Case Report.

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.
