Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Lymph nodes are small rounded structures which generate white blood cells where there is illness in the body. These lymph nodes are concentrated in some of the regions and the mediastinum is the place between two lungs and lymph nodes are found in this location when there is activation of immune system.

2. Your CT scan shows lymph nodes that have enlarged in size located in the mediastinum. This is close to the heart and great vessels. The mention of non necrotic lymph nodes explains that there is activity in the lymph node which is in reaction to a disease process.

3. The exact cause of the lymph nodes requires a FNAC or biopsy. These are pathological techniques used to confirm a disease.

4. To get a better idea of the seriousness of the lymph node enlargement in the mediastinum, it is important to read through the detailed CT scan report and seeing the pictures if possible.

5. Though most are not due to serious causes, there are patients who might develop this due to a life threatening disease like cancer or tuberculosis. Early diagnosis and treatment usually help most patients make a complete recovery.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek
