A. Rasheed, E. L. Palmer, E. A. Drucker, R. A. Novelline] Acute pulmonary embolus is a common problem requiring evaluation in the emergency setting. Following the initial chest radiograph, the most common imaging test requested is the ventilation perfusion lung scan. We describe a patient with sarcoidosis and a false positive ventilation perfusion lung scan caused by bilateral hilar adenopathy compressing the proximal pulmonary arteries. This case illustrates that patients with hilar adenopathy and suspected pulmonary embolus may have unreliable ventilation perfusion scans, and should be referred to arteriography or CT for evaluation, rather than for a ventilation perfusion lung scan.
