Abstrakt: Extrinsic lipoid pneumonia (ELP) results from the aspiration of lipid-containing substances. Tissue or cell histopathology after Oil-Red-O staining can confirm the diagnosis, which requires proper tissue handling and preparation during bronchoscopy. Here, we report a case of ELP in a quadriplegic patient with a long history of dysphagia and polyethylene glycol consumption. Computed tomography (CT) of the chest revealed multiple, progressively enlarging, fat-attenuated, nodular pulmonary lesions. Bronchoscopy with bronchoalveolar lavage (BAL) and a transbronchial forceps biopsy confirmed the diagnosis of lipoid pneumonia. We discuss the clinical, radiological, and pathological features of ELP and highlight the preparatory steps required for obtaining a successful diagnosis.
