<s>[INST] I have cysts multiple subcentimeter lymph nodes in the left axillary region. Could you explain where and exactly what this means. I have paperwork that states that my coronary arteries appear grossly perfused and sections of the lung demonstrate a tiny subpleural 0.5 cm nonsolid opacity within the anterior aspect of the right middle lobe. Could you explain the to me? [/INST] Thanks for your question on Chat Doctor. Lymphnodes in maxilla can be due to 1. Infection2. Benign enlargement3. Malignant spread. Since you are also having pleural based lesion on CT thorax, possibility of either infection or malignant lesion is there. So better to get done ultrasound guided FNAC (fine needle aspiration cytology) or biopsy from the Lymph nodes. This will diagnose the problem and start treatment accordingly. </s>
