These cysts are mostly found in young adults and are rare in infancy. The usual symptoms are the result of compression by the cyst, e.g., difficulty breathing or swallowing, cough, and chest pain. Malignant degeneration has been reported in these cysts on rare occasions. Bronchogenic cysts are usually found in the middle mediastinum.
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.
Patients presenting with no symptoms, and not affected by the syndrome may not require treatment. Corticosteroids have been reported to be of benefit in select patients. Bronchodilators may assist with breathing issues.
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]
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 ...
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.
Other names: lymphangiomyomatosis, LAM: Figure A shows the location of the lungs and airways in the body. The inset image shows a cross-section of a healthy lung. Figure B shows a view of the lungs with LAM and a collapsed lung (pneumothorax). The inset image shows a cross-section of a lung with LAM. Specialty: Pulmonology
Appearance of usual interstitial pneumonia (UIP) in a surgical lung biopsy at low magnification. The tissue is stained with hematoxylin (purple dye) and eosin (pink dye) to make it visible. The pink areas in this picture represent lung fibrosis (collagen stains pink). Note the "patchwork" (quilt-like) pattern of the fibrosis.
