Pemberton's sign was named after Hugh Pemberton, who characterized it in 1946.[1]
The Pemberton maneuver is a physical examination tool used to demonstrate the presence of latent pressure in the thoracic inlet.[2] The maneuver is achieved by having the patient elevate both arms (usually 180 degrees anterior flexion at the shoulder) until the forearms touch the sides of the face. A positive Pemberton's sign is marked by the presence of facial congestion and cyanosis, as well as respiratory distress after approximately one minute.[3]

Causes
A positive Pemberton's sign is indicative of superior vena cava syndrome (SVC), commonly the result of a mass in the mediastinum. Although the sign is most commonly described in patients with substernal goiters where the goiter “corks off” the thoracic inlet,[4] the maneuver is potentially useful in any patient with adenopathy, tumor, or fibrosis involving the mediastinum. SVC syndrome has been observed as a result of diffuse mediastinal lymphadenopathy of various pathologies such as cystic fibrosis [5] and Castleman’s disease.[6] Park et al. reported enlarged cervical lymph nodes associated with hemophagocytic lymphohistiocytosis as the cause of internal jugular vein compression, which presented clinically similar to SVC syndrome.[7]
