Abstract
Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of exogenous lipoid pneumonia associated with the use of mineral oil made and successfully managed by stopping the offending agent and supportive antibiotics.
Highlights
Lipoid pneumonia has been identified as a non-infectious cause of recurrent aspiration pneumonia in 12.5% cases
We describe an unusual and rare case of exogenous lipoid pneumonia secondary to aspiration of mineral oil used as a laxative for chronic constipation
Exogenous lipoid pneumonia should be considered a possible diagnosis in case of any nonresolving pneumonia
Summary
Lipoid pneumonia has been identified as a non-infectious cause of recurrent aspiration pneumonia in 12.5% cases. We describe an unusual and rare case of exogenous lipoid pneumonia secondary to aspiration of mineral oil used as a laxative for chronic constipation. A 66-year-old Caucasian female with a past medical history significant for multiple sclerosis, chronic constipation, and recurrent pneumonia presented to the emergency department (ED) with sudden onset of dyspnea. Prior to admission, she completed the course of broad-spectrum antibiotics for her third episode of pneumonia.
