Hence, entities generally not seen in natal people, such as cysts (Fig. 5) and you can fibroadenoma, could form [21, 22]. To our education, there are no composed training revealing the look of fibroadenoma in that it population, but we have seen two times on our very own business off fibroadenoma in the transgender female, hence, overall you’ll assume, have the same imaging appearance so you’re able to fibroadenoma found in natal women’s breasts (Fig. 6).
