If the vessels are difficult to see in the black lung as compared to the white lung, than it is likely that the black lung is abnormal 1-obstructive bronchiolitis chronic pulmonary embolism. If the vessels are the same in the black lung and white lung, then you are looking at a patient with infiltrative lung disease, like the one on the right with the pulmonary hemmorrhage 2-MOSAIC PERFUSION 2-AREAS OF DECREASED ATTENUATION WITHOUT WALLS (EMPHYSEMA ,MOSAIC PERFUSION ) Normal lung appearing relatively dense adjacent to lung with air-trapping (respiratory bronchiolitis, bronchiolitis obliterans). Bronchiolitis obliterans is seen in: Infectious (viral, mycoplasma) Chronic bronchitis Inhalation of toxin, fume (cigarette smoke) RA, Sj?gren Post transplant Drug reaction (penicillamine) What is the major abnormality in this case? a) Linear opacitiesb) Nodulesc) Consolidationd) Ground-glass opacity F = mediastinal end of the right major interlobar fissure . The major abnormality is the presence of nodules. Also present are linear abnormalities (answer a): thickened fissures, bronchovascular interstitium, and interlobular septa. Answer 1-Find 3 pleural nodules in the right lung. 2-Find an example of thickened bronchovascular interstitium in the right lung. 3-Find thickened fissural pleura with nodules along the outer portion in the left lung. 4-Find interlobular septal nodules. F = mediastinal end of the right major interlobar fissure 1-Find 3 pleural nodules in the right lung. 2-Find an example of thickened bronchovascular interstitium in the right lung. 3-Find thickened fissural pleura with nodules along the outer portion in the left lung. 4-Find interlobular septal nodules. F = mediastinal end of the right major interlobar fissure What is the distribution of the major abnormality? a) Bronchovascular interstitiumb) Interlobular septac) Centrilobular regiond) Pleura Answer The distribution of the nodules includes all of the regions listed although
