How is a 0.7cm hyperechoic parathyroid adenoma treated? too small to need removed? could this be cause of palpable supraclavicular node? mri this wed.

Depends on bloodtest: The concern with parathyroid adenomas is they often produce too much parathyroid hormone which regulates calcium blood levels. Loss of bone density and high calcium levels result. Some adenomas only cause a slight increase and can be safely monitored with blood tests while others require surgical removal. Highly unlikely to be cause of node.
