Dear sir, I have done neck ultrasound and it shows below findings- there are few small lymph nodes with intact fatty hilum, measuring 9 mm seen at right level 1b, measuring 11x7 mm at level ii and measuring 14x8 mm seen at level 1 b on left. Small lymph nodes, measuring 3.5 mm &6.0 mm in right intra parotid region and small lymph node measuring 6.2 mm (in sad) seen in posterior triangle. So I wanted to if it is normal lymph nodes or biopsy is required?
