BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration(EBUS-TBNA)is a safe and minimally invasive diagnostic tool for mediastinal and hilum evaluation.However,infectious complications may occur after EBUS-TBNA.Among these,mediastinitis and pericarditis are rare.CASE SUMMARY A 67-year-old woman was referred to our hospital due to paratracheal lymph node enlargement on chest computed tomography(CT).EBUS-TBNA was performed on the lymph node lesions,and prophylactic oral antibiotics were administered.Seven days after EBUS-TBNA,the patient visited the emergency room with a high fever and chest pain.Laboratory test results revealed leukocytosis with a left shift and elevated C-reactive protein level(25.7 mg/dL).Chest CT revealed the formation of a mediastinal abscess in the right paratracheal lymph node and pericardial and bilateral pleural effusions.The patient received intravenous antibiotic treatment,cardiac drainage through pericardiocentesis,and surgical management.The patient recovered favorably and was discharged 31 d after the operation.CONCLUSION Mediastinitis and pericarditis after EBUS-TBNA are rare but should be considered even after the use of prophylactic antibiotics.
