I have two slightly enlarged level 2 (one on each side) lymph nodes - rounded in morphology, hypoechoic and no internal vascularity. thoughts of cause?

Located? Use HTPrime: Lymph nodes without symptoms are hard to figure out. Causes for lymph nodes include old infection, lymphoma, other cancers / malignancy, inflammation, or congenital (you're "born that way"). The only way to know with certainty is by biopsy, but weigh risk of surgery w/ symptoms before going that route. Use HealthTap Prime to discuss your symptoms & get better guidance. Thanks for asking. Good luck
