{Reference Type}: Case Reports {Title}: Severe mediastinitis over a month after endobronchial ultrasound-guided transbronchial needle aspiration. {Author}: Kurokawa K;Asao T;Ko R;Nagaoka T;Suzuki K;Takahashi K; {Journal}: Respirol Case Rep {Volume}: 7 {Issue}: 5 {Year}: Jul 2019 暂无{DOI}: 10.1002/rcr2.426 {Abstract}: Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been reported to be a minimally invasive and relatively safe procedure, mediastinitis is a serious complication related to the procedure. The median time of mediastinitis onset is approximately 12 days after EBUS-TBNA. Here we report two rare cases with mediastinitis onset 40 and 53 days after EBUS-TBNA. Surgical drainage was performed since systemic treatment with antibiotics was insufficient in both cases. Eikenella corrodens, which is a slow-growing microorganism, was identified as the causative pathogen in one case. To our knowledge, this is the first report of mediastinitis occurring over a month after EBUS-TBNA. Clinicians should consider the diagnosis of mediastinitis even if symptoms appear over a month after EBUS-TBNA.
