Large, right lower lobe pneumatocele is shown, compromising ventilation in a premature infant with RDS and superimposed RSV pneumonitis. A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation. [1] Gas-filled, or air-filled lesions in bone are known as pneumocysts. [2]
Because the lung is elastic, the tear forms a round cyst called a traumatic air cyst that may be filled with air, or blood and air, and that usually shrinks over a period of weeks or months. [13] Lacerations that are filled with air are called pneumatoceles , and those that are filled with blood are called pulmonary hematomas . [ 14 ]
Diagnosis of a lung cavity is made with a chest X-ray or CT scan of the chest, [2] which helps to exclude mimics like lung cysts, emphysema, bullae, and cystic bronchiectasis. [5] Once an imaging diagnosis has been made, a person’s symptoms can be used to further narrow the differential diagnosis .
A lung cyst, or pulmonary cyst, encloses a small volume of air, and has a wall thickness of up to 4 mm. [3] A minimum wall thickness of 1 mm has been suggested, [3] but thin-walled pockets may be included in the definition as well. [4] Pulmonary cysts are not associated with either smoking or emphysema. [5]
A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness. [1] A bleb has a wall thickness of less than 1 mm. [2] By radiology definition, it is up to 1 cm in total size. [3]
CT scan in a patient with usual interstitial pneumonia, showing interstitial thickening, architectural distortion, honeycombing and bronchiectasis.. In radiology, honeycombing or "honeycomb lung" is the radiological appearance seen with widespread pulmonary fibrosis [1] and is defined by the presence of small cystic spaces with irregularly thickened walls composed of fibrous tissue.
Biological vs. chronological age Chronological age is the one most of us are familiar with — it’s the number of years since you were born. Biological age, however, measures how well someone is ...
A pulmonary hematoma is a collection of blood within the tissue of the lung. It may result when a pulmonary laceration fills with blood. [1] A lung laceration filled with air is called a pneumatocele. [1] In some cases, both pneumatoceles and hematomas exist in the same injured lung. [2]
