Active TB Cavitation and Ipsilateral Transbronchial Spread with Extensive Tree in Bud Pattern
39-year-old immigrant Vietnamese male presents night sweats fever and cough
CXR shows a cavitating lesion in the apex of the right lung (magnified lower image, right) associated with an ipsilateral micronodular pattern (magnified lower image, left)
Although the right lung has the appearance of a “miliary” pattern, this term is usually referred to the hematogenous spread of the disease

39-year-old immigrant Vietnamese male presents night sweats, fever, and cough. CT in the coronal plane of the chest shows a large cavitating lesion in the right upper lobe, with innumerable micronodules dominantly in the right midlung field, and to lesser extent in the right upper lung field. Some micronodules are probably present in the left lower lobe as well. Close to the largest subsegmental consolidation there is a bronchus which shows thickening of its wall.

Active TB Transbronchial Spread with
39-year-old immigrant Vietnamese male presents night sweats fever and cough. CT in the axial plane through the mid chest shows innumerable micronodules resulting from transbronchial spread with resultant tree in bud pattern scattered through the right lung (magnified in the right lower image). There are minimal similar changes in the lingula (magnified left lower image)..
