I was dxed with a adrenal adenoma years ago. i just had a c-scan done and it showed a small nodule on the adrenal, not neeting the criteria fora adenoma? i am confused.

Diagnostic Criteria: change over time, as does CT technology. What was called an adenoma 20 years ago might qualify as a nodule by today's criteria. Also, there is a phenomenon called "interobserver variability," meaning that measurements and appearance of lesions on radiographs are judgement calls, and what one radiologist calls a nodule, another may call an adenoma. Hope this helps!
