Lung Cancer

Calcified granuloma

10/09/2008

Question:

Yes last year I had a ct scan and it revealed I had a calcified granuloma in my right lower lobe lung and several in my spleen. My doctor said they are nothing and not to worry about it but in the back of my head I still think about it every day and wonder what if it is something if you could give me any information on this matter I would appreciate it. I`m a 28yr old male white live in southwest virginia the granuloma in my lung was 1.5cm and they didn`t give a size in the spleen just said tiny punctuate calcification granulomas thank you for your time

Answer:

A calcified granuloma usually signifies a benign condition. Most likely in your case this is from a previous fungal infection known as histoplasmosis. This is very common in the midwest. If these calcified lesions are present in spleen in addition to lung, it is most likely not cancer. However, if you had non-calcified lesions in the lung then one would entertain the idea of possible cancer or infection or other immunologic conditions. Depending on the size of the non-calcified lesions we may either decide to obtain a biopsy or follow with periodic CT scans. Not sure if you have any clinical symptoms or what prompted you to get the CT. In your case calcified granuloma in spleen and right lower lobe is probably benign. Your physician most likely weighed in all the risk factors (smoking status, age, type of lesion (calcified vs non-calcified)) before recommending the management plan.
