A 65-y-old Japanese man was referred to the respiratory medicine department because of abnormal radiologic findings. High-resolution chest computed tomography scans revealed a geographic distribution of ground-glass opacities and associated thickening of the interlobular septa (crazy-paving patterns) in both lower lobes. He had a habit of drinking 400-500 mL of milk and 400-800 mL of canned coffee with milk every day. A swallowing function test revealed liquid dysphagia. Bronchoalveolar lavage fluid cytology findings showed multiple lipid-laden macrophages. Taken together, these findings revealed exogenous lipoid pneumonia. We performed bronchoscopic segmental lavage therapy 3 times in the left lung. After the treatment, the radiologic findings improved in both lungs. The patient has not experienced a recurrence of lipoid pneumonia in 2 y to date. In conclusion, a case of exogenous lipoid pneumonia was successfully treated with bronchoscopic segmental lavage therapy.
