Lipoid pneumonia natural history, complications and prognosis
Introduction
Overview
Overview
Patients might present acutely with inflammation and cough, fever, and dyspnea. However, they might be asymptomatic and present with an incidental mass on radiographs. Due to its nonspecific symptoms and radiological features, lipoid pneumonia often remains undiagnosed or diagnosis is delayed. The oil released illicits a giant-cell granulomatous reaction (hence also called lipid granulomatosis), chronic inflammation, and alveolar and interstitial fibrosis. Evolution of lesions with time has been described: Fresh lesions show alveolar infiltration by lipid-laden macrophages and almost normal alveolar walls and septa, and advanced lesions show larger vacuoles and inflammatory infiltrates in alveolar walls, bronchial walls and septa.
