title: Transient bronchoconstriction associated with angiographically proven pulmonary embolus.
abstract: It is rare for a pulmonary embolus to cause delayed washout on xenon scans. A case of angiographically proven pulmonary embolus with transient bronchospasm present 48 hours after the onset of symptoms is presented. Possible mechanisms are discussed.
