What does steeple sign mean?

In radiology, the steeple sign is a radiologic sign found on a frontal neck radiograph where subglottic tracheal narrowing produces the shape of a church steeple within the trachea itself. The presence of the steeple sign supports a diagnosis of croup, usually caused by paramyxoviruses.

What is stipple sign?

The stipple sign refers to the pointillistic end-on appearance on intravenous pyelography or retrograde pyelography of contrast material tracking into the interstices of a papillary lesion.

What is croup called?

Croup is an inflammation of the larynx and trachea, mostly seen in young children. A barking cough, varying degrees of airway obstruction, and hoarseness are the defining symptoms. A range of infectious conditions can lead to croup. It is also known as laryngotracheobronchitis.

• difficulty and pain when swallowing.
• difficulty breathing, which may improve when leaning forwards.
• breathing that sounds abnormal and high-pitched (stridor)
• a high temperature.
• irritability and restlessness.
• muffled or hoarse voice.
• drooling.

What is thumbprint sign on xray?

What is the difference between stridor and croup?

The primary distinction: stridor is a sign of airway obstruction, whereas croup is a syndrome that can cause stridor. Airway obstruction, whether caused by croup or another condition, is an emergency situation that must be investigated fully and treated promptly to prevent a detrimental outcome.

What is the steeple sign in croup?

The steeple sign represents the glottic and subglottic narrowing of the airway typically seen in children with croup. In radiology, the narrowing of airway lumen alters the appearance of tracheal air column, which resembles a church steeple or a steeply pitched roof.

What is thumb sign?

The thumb sign in epiglottitis is a manifestation of an edematous and enlarged epiglottis which is seen on lateral soft-tissue radiograph of the neck, and it suggests a diagnosis of acute infectious epiglottitis. This is the radiographic corollary of the omega sign 1-3.

This respiratory illness, recognized by physicians for centuries, derives its name from an Anglo-Saxon word, kropan, or from an old Scottish word, roup, meaning to cry out in a hoarse voice. Croup is the most common etiology for hoarseness, cough, and onset of acute stridor in febrile children.
