Final answer:
The mammographic appearance of juvenile fibroadenoma can vary, but it typically appears as a well-defined, high-density mass with a smooth or lobulated border on mammography.
Step-by-step explanation:
Mammographic Appearance of Juvenile Fibroadenoma
In mammography, the appearance of juvenile fibroadenoma can vary, but it typically appears as a well-defined, round or oval mass with a smooth or lobulated border. Juvenile fibroadenomas often have a high density due to the presence of fibrous tissue and can sometimes have areas of calcifications. They tend to be more dense than surrounding breast tissue, which can make them stand out on a mammogram.
However, it's important to note that the appearance of fibroadenomas can vary between individuals, and other imaging modalities, such as ultrasound, may be used to further evaluate the characteristics of the mass.
