Lung granuloma

08/24/2001

Question:

My lung xray showed a granuloma in my left upper lung ...what is it?

Answer:

A pulmonary granuloma is a focal inflammatory lesion (think scar) resulting from a prior injury that is often the result of an infection. They are benign in that they are not cancer, but often have similar enough roentgenogram appearances so as to be confused for them. Sometimes the differentiation is quite easy and made on x-ray characteristics alone and sometimes it can only be determined by pathological investigation after resection of the granuloma.
