Here, we describe the case of a 56-year-old female @entity1 who was diagnosed with an anterior mediastinal cyst measuring 26 * 16 mm in size. An endobronchial ultrasound-guided transbronchial needle aspiration was performed, and punctures occurred three times. The @entity1 was then prescribed cefditoren pivoxil. Three days after the procedure, the @entity1 developed infective @entity1764 . Panipenem/betamipron, @entity3402 , and @entity1 immunoglobulin were administered, and her symptoms improved over 2 weeks. Five months after developing @entity1764 , surgical resection of the cyst was performed with inverted L-shaped mini-sternotomy. The @entity5409 strongly adhered to the surrounding tissues. The final pathological diagnosis was a @entity5619 . Endobronchial ultrasound-guided transbronchial needle aspiration is not a completely sterile procedure and can lead to severe infective complications in the mediastinum. Although this procedure may not be contraindication for use with mediastinal cystic lesions, physicians must take into account the risk of severe infective complications.
