Mediastinal abscess formation after EUS-guided FNA: Are patients with sarcoidosis at increased risk?

摘要

Sarcoidosis is a disease of unknown etiology mostly affecting young adults and presenting with mediastinal or hilar lymphadenopathy in 85% of patients. Endoscopic US-guided FNA (EUS-FNA) and endobronchial US-guided transbronchial needle aspiration (EBUS-TBNA) of in-trathoracic lymph nodes is increasingly used for the diagnosis of pulmonary sarcoidosis. Complications are rare-severe procedure-related infections have been reported in only 2 patients. One patient developed mediastinitis and another a mediastinal abscess after EUS-FNA.1'2 This case series describes 5 patients with suspected sarcoidosis who developed mediastinal abscesses after EUS-FNA, necessitating surgical treatment in 4 patients.
