Abstract

Exogenous lipoid pneumonia is a rare and under recognized pulmonary disorder caused by the inhalation or aspiration of fat-like substances. Nasal decongestants containing mineral oils or paraffin are emerging as overlooked etiological agents. This review consolidates existing literature to delineate the clinical, radiological, and pathological features of exogenous lipoid pneumonia induced by nasal decongestants, highlight diagnostic challenges, and underscore the importance of thorough patient history in early diagnosis and management. This condition, while preventable, can result in serious pulmonary complications if not recognized early. It necessitates a multidisciplinary approach that incorporates careful history taking, high-resolution imaging, cytological assessment, and public health vigilance.

Keywords: Lipoid pneumonia; Nasal decongestants; Pulmonology; Respiratory medicine; Infections

Core Tip: Exogenous lipoid pneumonia from nasal decongestants is a preventable but often missed diagnosis. Early recognition through detailed history and imaging is crucial to avoid serious lung complications.
