Could you please talk more about ascess within the lymph node itself ? How can you distinguish it from other abscesses ? If there is no color doppler within the lesion then how do you know that is a lymph node ?

An abscess shouldn’t have flow, it’s a fluid collection. A normal inflammatory lymph node has a flow pattern that looks like a small tree, with the tree trunk being the hilum of the lymph node and the branches of the tree spreading within the kidney beam shape of the lymph node. A lymph node is kidney beam shape in long and will be round in transverse. An abscess ha no distinct shape. Hope that helps.
