Abstract
A case of septic pulmonary emboli due to parenteral nutrition catheter infection was reported. Characteristic radiologic features were recognized.
A 50-year-old man, who was receiving parenteral nutrition after total gastrectomy, consulted our department with complaints of fever and general malaise. A chest radiograph showed scattered ill-defined small peripheral nodules, which were not present before parenteral nutrition, and these nodules were quickly cavitalized in 2nd day. He was suffering from high fever, hemosputum and dyspnea after removal of the parenteral nutrition catheter. Pseudomonas aeruginosa was isolated from the tip of parenteral nutrition catheter and sputum cultures. Septic pulmonary emboli were diagnosed and antibiotic therapy was performed. Bacterial endocarditis and septic thrombophlebitis were ruled out. The multiple cavitary nodules extended to involve the perpheral areas of the lung and invasive shadows appeared on the chest radiograph in 8th day. Then, the invasive shadows disappeared and the walls of the cavitary lesions became thinner. After 2 months, all cavitary lesions dissappeared with only linear shadows remaining.
