Overall CT findings are highly suspicious of active pulmonary tuberculosis. The presence of tree-in-bud appearance of randomly distributed lung nodules are usually associated with endobronchial spread of pulmonary tuberculosis, though they are not specific signs.
For tuberculosis patient who presents with hemoptysis and multiple lung cavities, the possibility of Rasmussen aneurysm should be suspected. CT pulmonary angiography is the investigation of choice. It will appear as focal dilatation of one of the pulmonary segmentary arteries adjacent to tuberculous parenchymal change or a tuberculous cavity.
