Going through the history and ultrasound reports, your mother has Chronic
liver disease as mentioned.
With minimal ascites.
I am not getting the exact cause for CLD? has it been evaluated for a precise diagnosis? Bcz multiple causes are there to cause CLD.
Subcentimetric lymph nodes it is a normal finding, so no need to worry and focus on that. Atleast not in this case
I would like to advise you to get a basic CBC,
LFT, RFT profile and consult a Gastroenterologist or a hepatologist (liver doctor) for a detailed follow up.
Best wishes . Take care
