What can a lit up pet scan in left subpectoral area mean in lymph node . ?

Several Things: A positive pet scan does not always equate with malignancy. The positive scan reflects increased metabolic activity. Causes of false positive exams include infectious diseases (mycobacterial (like tb), fungal, bacterial infection), sarcoidosis, radiation pneumonitis and post-operative surgical conditions have shown intense uptake on pet scan. Good luck!

It depends: It could be a reactive/benign lymph node from an infection...Or it could be a malignant/metastatic lymph node. I need more information about you and why you had the scan done.

Increased metabolism: Pet scans with a radioactive analog of glucose measure glucose metabolism. Uptake in a lymph node means that node is using glucose more that is normal. The reasons for that include infection, inflammation, primary malignancy or metastatic disease. Please see your health care provider for continued medical care.
