Abstract

Case Presentation: We describe a complete right hemithorax Westermark sign found in a patient with a near-complete, right pulmonary artery trunk occlusion secondary to a pulmonary embolus.

Discussion: We review the sensitivity and specificity of a Westermark sign in the identification of a pulmonary embolism, and how this aided us in managing our patient in the emergency department.
