title: Enlarging mediastinal/hilar lymphadenopathy with calcification.
abstract: A 77-year-old man was referred to our hospital due to enlarging mediastinal/hilar lymphadenopathy with calcification. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and bone marrow aspiration were performed. Subsequently, monoclonal gammopathy of undetermined significance (MGUS) associated with mediastinal amyloidosis was diagnosed. We hereby report a case in which EBUS-TBNA led to a successful diagnosis of amyloidosis.
