A CASE OF MEDIASTINAL ABSCESS CAUSED BY ENDOSCOPIC ULTRASOUND-GUIDED FINE NEEDLE ASPIRATION OF A MEDIASTINAL LESION

Abstract

A 78-year-old man was referred to our hospital with a posterior mediastinal lesion measuring 35 mm in diameter. We performed endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy of the mediastinal lesion using a 22-gauge needle. The patient was discharged the next day. Seven days later, the patient contacted the hospital with chief concerns including fever, chest pain, and dysphasia. Chest computed tomography showed widening of the mediastinum with an abscess and air. Urgent debridement surgery was performed and the patient was discharged 28 days postoperatively. This case report describes a patient who developed life-threatening mediastinitis after EUS-FNA of a mediastinal lesion.
