BISPO, Miguel et al. Mediastinal Abscess Formation after EUS-Guided Sampling in a Young Patient with Sarcoidosis: Be Aware of the Increased Risk!. []. , 30, 2, pp.14-17.   01--2024. ISSN 2341-4545.  https://doi.org/10.1159/000526508.

International guidelines establish EUS-guided sampling as safe and accurate for the evaluation of mediastinal solid lesions, such as lymphadenopathies of unknown origin, and point out an increased risk of severe infectious complications induced by needle puncture in mediastinal cystic lesions. A retrospective case series and a systematic review documented an increased risk of mediastinal abscess formation after EUS-guided lymph nodes sampling in patients with sarcoidosis. The authors describe a case of a 38-year-old male patient with a final diagnosis of sarcoidosis, who developed a large mediastinal abscess after EUS-guided fine-needle biopsy of mediastinal lymphadenopathies. Endoscopists should be aware of the potential increased risk of severe infectious complications when sampling mediastinal lymph nodes in suspected sarcoidosis, and a strategy to minimize such risk should be pursued.
