As a medical professional with expertise in neurology, I can provide you with an accurate description of Quincke's sign.
Quincke's sign, also known as the "pulsating jugular" sign, is a clinical finding that is indicative of increased intracranial pressure (ICP). It is observed when a patient with a condition that raises intracranial pressure, such as a brain tumor or cerebral hemorrhage, has a visible pulsation in the jugular veins of the neck. This pulsation is synchronous with the arterial pulse and can be seen or felt through the skin, particularly when the patient is in a recumbent position.
The sign is named after the German physician Heinrich Irenaeus Quincke, who first described it in 1891. It is important to note that Quincke's sign is not pathognomonic for any single condition but is rather a sign that can be associated with various conditions that lead to increased ICP.
To observe Quincke's sign, a healthcare provider will typically look for the pulsation in the neck veins while the patient is lying down, with the head of the bed elevated to about 30 degrees. The presence of this sign may prompt further diagnostic evaluation to determine the underlying cause of the increased ICP.

Quincke's pulse is a physical finding of severe and chronic aortic insufficiency. Regurgitant blood flow into a dilated left ventricle during diastole leads to a decrease in diastolic pressure and a consequent increase in stroke volume, resulting in blanching and flushing, respectively, of the nail bed.
