Paraquat (1,1'-dimethyl-4,4'-dipyridylium) is a liquid herbicide, linked to both accidental and intentional ingestion, which can result in severe and frequently lethal poisoning. It has been known to cause injury to the lungs, kidneys, and liver. We retrospectively reviewed five cases over the last 4 years with a history of paraquat ingestion. The time duration between ingestion and high-resolution computed tomography (HRCT) was assessed. HRCT chest scan was variable, ranging from 4 to 18 days postexposure. The follow-up of the patients was also reviewed.
