We report the case of a 32-year-old welder who developed a flu-like syndrome a few hours after founding zinc. The patient experienced fever, headache, muscle pain and dyspnea that resolved spontaneously with a few hours. The diagnosis of metal fume fever was retained. The chest x-ray evidenced bilateral diffuse infiltrative pulmonary lesions, rarely described in this syndrome. Metal fume fever is a likely diagnosis in exposed patients who develop fever with diffuse lung involvement.
