Final answer:
Right supraclavicular adenopathy refers to the enlargement of lymph nodes on the right side of the supraclavicular area, while left supraclavicular adenopathy refers to the enlargement of lymph nodes on the left side of the supraclavicular area.
Step-by-step explanation:
The difference between right and left supraclavicular adenopathy is the location of the enlarged lymph nodes. Right supraclavicular adenopathy refers to the enlargement of lymph nodes on the right side of the supraclavicular area, while left supraclavicular adenopathy refers to the enlargement of lymph nodes on the left side of the supraclavicular area. The supraclavicular area is located just above the collarbone, and the lymph nodes in this area can be an indication of infection or other medical conditions.
