Mediastinal abscess formation after EUS-guided FNA in patients with sarcoidosis

Mediastinitis after EUS-FNA in a Patient with Sarcoidosis – Case Report with Endosonographic Features and Review of the Literature

“…Bartheld et al [2] speculated, that the amount of regulatory T-cells at the periphery of sarcoid granulomas could lead to an increased local infection risk. In addition, small intranodular hematoma after EUS-FNA, or partly necrotic lymph nodes, probably provide a good medium for secondary bacterial growth [3,22]. In our patient, we performed two EUS-FNA of mediastinal lymph nodes at different times: a first FNA two years earlier, before adjuvant chemotherapy and operation, to rule out metastatic disease, was done without any complication.…”
