Lung diseases

Biapical parenchymal scarring



What is biapical parenchymal scarring? And what do you do about it? (it was noted on my CT scan)


This means that there is scar in the apical portions of the lung which are the very top-most parts of the lung. This is often due to previous infection, such as previous pneumonia or tuberculosis. In persons who live in the Midwestern United States, it is often due to past infection by the fungus, histoplasmosis. It can also be due to some rare autoimmune conditions as well. Most of the time, if there is no sign of autoimmune disease or active infection, we do a TB test and if negative simply follow patients without doing a lung biopsy or a bronchoscopy.
