Westermark Sign
Westermark Sign (pronunciation: west-er-mark sign) is a clinical sign often used in the field of medicine to indicate the presence of pulmonary embolism. It is named after the Swedish radiologist, Nils Westermark, who first described it in 1938.
Etymology
The term "Westermark Sign" is derived from the name of its discoverer, Nils Westermark, a Swedish radiologist. He first described this sign in 1938 while studying the radiological findings in patients with suspected pulmonary embolism.
Definition
Westermark Sign refers to a region of decreased lung markings distal to a pulmonary embolus, which is often associated with an abrupt cut-off of the pulmonary artery, also known as the Palla's sign. It is one of the signs that can be seen on a chest radiograph or a computed tomography (CT) scan of the chest.
