Mediastinitis after EUS-FNA in a patient with sarcoidosis - case report with endosonographic features and review of the literature.

摘要

EUS-FNA, but not EBUS-FNA, seems to be associated with an increased infectious risk in patients with sarcoidosis. Endosonographic features include inhomogeneous, mass-forming mediastinal infiltration, and swelling of lymph nodes with hyperechoic central parts. In cases of suspected sarcoidosis, EBUS-FNA should be preferred. EUS-FNA, probably with antibiotic prophylaxis, should only be done after a non-diagnostic bronchoscopic work-up.
