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.
Bronchiectasis without CF is known as non-CF bronchiectasis. Historically, about half of all cases of non-CF bronchiectasis were found to be idiopathic , or without a known cause. [ 25 ] However, more recent studies with a more thorough diagnostic work-up have found an etiology in 60 to 90% of patients.
When found in the lungs, tram tracks are radiologic signs that are usually accompanied by pulmonary edema in cases of congestive heart failure and bronchiectasis. Tram tracks are caused by bronchial wall thickening, and can be detected on a lateral chest X-ray. [1]
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction.Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.
The chest X-ray and classification worksheet by the Centers for Disease Control and Prevention (CDC) of the United States is designed to group findings into categories based on their likelihood of being related to TB or non-TB conditions needing medical follow-up.
Furthermore, Takeda et al. showed that the 1, 2, 3, and 5-year hemostatic rates of bronchiectasis (without nontuberculous mycobacteriosis or pulmonary aspergillosis) were 91.3, 84.2, 81.5, and 78.9%, respectively. [15] This paper is valuable for its long-term results of 5 years.
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
