What is a Hampton hump?
Hampton’s hump is a radiological sign consisting of a peripheral, wedge-shaped opacification adjacent to the pleural surface, which represents pulmonary infarction distal to a pulmonary embolus. 1. Owing to good pulmonary perfusion from collateral blood vessels, this sign is rarely seen in clinical practice.

What causes infarction in the lungs?
A pulmonary infarction, also called lung infarction, occurs when a section of lung tissue dies because its blood supply has become blocked. While several medical conditions can cause a pulmonary infarction, the most common cause is pulmonary embolus.
What is focal Oligemia?
Westermark sign is a chest x-ray finding of oligaemia (clarified area) distal to a large vessel that is occluded by a pulmonary embolus. The focal area of increased translucency due to oligaemia is caused by impaired vascularisation of the lung due to primary mechanical obstruction or reflex vasoconstriction.
How do you detect a PE?
How is a pulmonary embolism diagnosed?
- a computerised tomography pulmonary angiography (CTPA) to see the blood vessels in your lungs.
- a ventilation-perfusion scan, also called a V/Q scan or isotope lung scanning, to examine the flow of air and blood in your lungs.
Can you see a PE on an ECG?
2 The ECG is often abnormal in PE, but findings are neither sensitive nor specific for the diagnosis of PE.
What is Plethoric lung?
Plethoric lung fields are indicative of increased pulmonary blood flow and are seen in left-to-right shunts. The pulmonary artery branches are prominently seen up to peripheral lung fields and flow is significantly increased.
What causes Oligemia?
Oligemia may be caused by atrial-pulmonary-vascular reflex vasoconstriction, low right ventricular output, and possibly high levels of atrial natriuretic factor.
Does a lung infarction heal?
Infarcts that do not heal within two or three days generally take two to three weeks to heal. The dead tissue is replaced by scar tissue.
Is a lung infarction painful?
If pulmonary infarction occurs, the person may cough with blood-stained sputum, sharp chest pain when breathing in, and in some cases fever. Symptoms of infarction often last several days but usually become milder every day.
What kind of pulmonary embolism has a Hampton hump?
A Hampton hump in a person with a right low lobe pulmonary embolism. This person also has a ported central venous catheter Hampton’s hump, also called Hampton hump, is a radiologic sign which consists of a shallow wedge-shaped opacity in the periphery of the lung with its base against the pleural surface. [1]
How did Hampton’s hump get its name?
Hampton’s hump, also called Hampton hump, is a radiologic sign which consists of a shallow wedge-shaped opacity in the periphery of the lung with its base against the pleural surface. [1] It is named after Aubrey Otis Hampton, who first described it in 1940. [2]
What causes a hump in the upper back?
The takeaway Kyphosis is a condition where the spine curves at an increased angle, causing a rounding or hump to form around the upper back or shoulders. There are many possible causes of kyphosis, including aging, poor posture, and spinal conditions. In the past, kyphosis was referred to as “dowager’s hump”.
What are the radiographic features of Hampton’s hump?
(B) A wedge-shaped peripheral consolidation (black arrowhead) was identified more peripheral to the previously described filling defect, producing the Hampton’s hump seen on radiography.
