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]
Congenital pulmonary airway malformation, formerly called congenital cystic adenomatoid malformation, is a benign tumor the results in the formation of single or multiple cysts. [2] Pulmonary sequestration refers to abnormal lung tissue that gets its blood supply from the systemic circulation instead of the pulmonary circulation, like the rest ...
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 lung cavity has a wall thickness of ...
Thin-walled cystic change in the lungs may be found incidentally on CT scans of the heart, chest or abdomen (on the cuts that include lung bases) obtained for other purposes. HRCTs of TSC patients reveals that about 20% of women have cystic change by age 20 and about 80% of women have cystic changes after age 40. [ 79 ]
Their walls are thin, being less than 1 mm thick. If they rupture, they allow air to escape into pleural space, resulting in a spontaneous pneumothorax and possibly a collapsed lung. [1] [2] Blebs can grow larger or join together to create a larger cyst, or bulla. There are usually no symptoms unless a pneumothorax occurs or the bulla grows ...
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.

[5] [10] The cysts do not cause other symptoms [5] and lung function is usually normal. [6] More than 83% of people with BHD have cysts, but the syndrome does not cause conditions like progressive chronic obstructive pulmonary disease or generalized respiratory failure, [2] though it does cause emphysema.
