This CT shows a prominent calcification in the right middle lobe, consistent with granulomatous disease, either TB or histoplasmosis. Note however that the calcification is eccentric and thus it is essential to follow this up on the 3/6/12month/1 year protocol. The presence of a calcified ipsilateral hilar node in this case makes granulomatous disease more likely. (30249 30252 30252c)

This CT shows a prominent calcified node in the right hilum, and a calcification in the RML consistent with granulomatous disease, either TB or histoplasmosis. In this case the calcification in the lung is eccentric and hence it has to be closely followed, although given the calcified hilar node malignancy is extremel unlikely.

This is a CT scan show a cavitating mass in the superior segment of the left lower lobe, that also has an eccentric calcification. This is a classical example of squamous cell carcinoma of the lung. The calcification is unusual.
