Vaping Induced Pathological Changes In The Lung Comparing With Imaging Finding-A Case Report Study

Vaping Associated Pulmonary Injury (VAPI) is a group of respiratory symptoms like shortness of breath and tachypnea and, oftentimes, it is associated with non-specific symptoms like generalized fatigue, body ache, fever, nausea, diarrhea, vomiting and chills. This entity has been previously categorized as a diagnosis of exclusion and best described as an exogenous lipoid pneumonia, or chemical pneumonitis. Exogenous lipoid pneumonia has characteristic finding in histology where inhaled fatty substances are recognized with special stain versus endogenous lipoid pneumonia, which is due to airway obstruction giving histology look of cholesterol crystals and accumulated debris. Here we describe the onset of an exogenous cause of lipoid pneumonia in an otherwise healthy patient using cannabis-containing products. We explore, similarities in the clinical case, identify common clinical features, characteristic radiologic findings along with cytological changes in the lungs.
