일주일간 항생제 치료를 하였으나 흉부 x선 검사에서 우중엽의 원형 경화병변이 악화되는 소견을 보여 piperacillin/tazobactam으로 항생제를 변경하였다.
Antibiotic treatment was performed for a week, but the chest x-ray revealed that the circular sclerotic lesion in the right middle lobe was worsening, so the antibiotic was changed to piperacillin/tazobactam.
