Complete lung collapse as a rare complication of sarcoidosis-associated mediastinal lymphadenopathy

Abstract

Complete lung collapse associated with sarcoidosis is exceedingly rare. Although lymphoma should be ruled out when patients with mediastinal lymphadenopathy develop lung collapse, sarcoidosis should be considered in the differential, especially when associated with fibrosing mediastinitis.

Keywords: Atelectasis; fibrosing mediastinitis; lymphadenopathy; lymphoma; sarcoidosis.
