We reported on a rare case of morning glory seeds as bronchial foreign bodies. The patient was a five-month-old male infant. He accidentally inhaled morning glory seeds after placing them in his mouth and coughing. The consulting doctor diagnosed that he had caught a cold after examining a chest x-ray image and observing normal sounding respiration. Three days later, his body temperature was 40 degrees and his cough was persisting. Medical consultation was sought again. His chest x-ray revealed that the mediastinum had moved to the right side and the left pulmonary field had inflated abnormally. CT imaging clearly indicated foreign bodies in the left bronchus. We performed a ventilation bronchoscopy. His left bronchus was obstructed by morning glory sprouts. After we removed the sprouts, the child's respiratory sound and chest x-ray results improved. We determined that the morning glory seeds had germinated in the warm and wet bronchus and the enlarged seeds had obstructed his left bronchus.
