Transient bronchoconstriction associated with angiographically proven pulmonary embolus
Clinical Nuclear Medicine
|June 1, 1985
Summary
Pulmonary embolism rarely causes delayed xenon scan washout. This case highlights transient bronchospasm occurring 48 hours after symptoms, suggesting unusual mechanisms for pulmonary emboli.
Area of Science:
- Pulmonary Medicine
- Radiology
- Respiratory Physiology
Background:
- Pulmonary embolism (PE) is a common and serious condition.
- Xenon ventilation scans are used to assess lung perfusion and ventilation.
- Delayed washout on xenon scans is an uncommon finding in PE.
Observation:
- A case of a patient with angiographically proven pulmonary embolism is presented.
- The patient exhibited transient bronchospasm 48 hours after symptom onset.
- This delayed respiratory symptom is unusual for pulmonary embolism.
Findings:
- The pulmonary embolism was confirmed through angiography.
- Delayed xenon scan washout was observed, which is a rare finding in PE.
- Transient bronchospasm persisted for 48 hours post-symptom onset.
Implications:
- This case suggests that pulmonary embolism can have varied and delayed presentations.
- Understanding these atypical presentations is crucial for accurate diagnosis and management.
- Further research into the mechanisms of delayed bronchospasm in PE is warranted.
