Granuloma of lung: A granuloma of the lung is the result of an inflammation of the lung. They may be due to infectious processes like TB or sarcoidosis. Fungi such as histoplasmosis or coccidimycosis or may be due to a cancerous tumor. You will need further studies such as a MRI or ct scan. A needle biopsy may also be needed to determine the cause. Good luck!

Many causes: The 2 mm granuloma is benign and nothing to worry about. Read here for more info - http://news.Cancerconnect.Com/what-is-a-lung-granuloma/ unless the 8 mm lobulated well defined nodule contains fat (benign hamartoma) or calcified (likely another benign granuloma), it will require a follow up ct (in 3-6 months). This is assuming you don't have a known primary malignancy that you haven't mentioned.
