2025年1月17日 · While the tree-in-bud pattern usually represents an endobronchial spread of infection, given the proximity of small pulmonary arteries and small airways (sharing branching morphology in the bronchovascular bundle), a rarer cause of the tree-in-bud pattern is infiltration of the small pulmonary arteries/arterioles or axial interstitium 3,6,7.

2025年1月22日 · Endobronchial spread along nearby airways is a relatively common finding, resulting in relatively well-defined 2-4 mm nodules or branching lesions (tree-in-bud sign) on CT 1,3. Hilar nodal enlargement is seen in only approximately a third of cases 1 .

2024年10月31日 · Endobronchial lesion Primary tracheal and endobronchial lesions occur within the tracheal or bronchial lumen 8 . They are rare and are more commonly malignant than benign ref .

2021年7月12日 · Endobronchial tuberculosis is an infection along the bronchial walls +/- involvement of the lumen by tuberculosis. It may affect any part of the bronchial tree.

2024年12月19日 · endobronchial blood or blood clot appears similar to mucus plugging on CT in some situations, there can be overlap between some endobronchial tumors per se (rather than with associated mucoid impaction)

2024年3月6日 · Broncholith refers to focal calcified endobronchial material which usually follows erosion by a granulomatous peribronchial lymph node (e.g. TB) 13. This can cause distal atelectasis, bronchiectasis or mucoid impaction.

2023年10月4日 · An endobronchial blocker (also sometimes referred to a bronchial blocker) is a flexible tube with an inflatable balloon at its distal end. The device is purposefully inserted into the proximal aspect of a main bronchus to induce one lung ventilation.

2024年12月18日 · In upper lobe cavitary form, thin-walled cavities with overall volume loss and fibrosis are the dominant feature, often also with features of endobronchial spread with tree-in-bud opacities seen elsewhere.
