Thank you for asking your query at DoctorSpring.
I have gone through the attached report. Unfortunately the report only gives me limited information. Ultrasound is a 'live' procedure (more like a video). The report will be a synopsis only.
However considering that you are having a painless, non growing selling for 1 yr - it is mostly suggestive of Benign (non cancerous swelling). Considering this fact , I would say there is not much urgency. You can discuss with your Doctor whether the swelling is amenable to a FNAC (Fine needle aspiration cytology). This might give a better picture than the CT. (CT result again can be inconclusive. FNAC can give a tissue diagnosis. And even after CT you may have to go for a FNAC. Possibilities are what your Doctor has mentioned - Lymphnodes or benign salivary glands swellings.
Hope this helps
