π©Ί Practical Clinical Tip
Size alone is not diagnostic.
Eccentric cortical thickening and loss of fatty hilum are more concerning than symmetric mild thickening.

π English Summary
Normal axillary lymph nodes usually have cortical thickness less than 3 mm with preserved fatty hilum.
Cortical thickness above 4β5 mm, especially with eccentric thickening and hilum loss, increases suspicion and may require biopsy.
Morphology is more important than size alone.
