Fibroadenomas are the most common benign breast lesions in women. Hormonal activities, particularly an increase in oestrogenic activity, have an important role in the aetiology of fibroadenomas. They are commonly detected incidentally. Most fibroadenomas have similar imaging findings and these lesions can be defined as simple fibroadenomas (SFAs). However, due to different histopathologic characteristics and components, variants of fibroadenomas have been described. These variants include; juvenile, giant, complex, myxoid, cellular, and hyalinised fibroadenomas. The diagnoses of these variants are important. They have different clinical behaviours, potential for malignant transformation, and treatment strategies. We present imaging findings of SFAs and other variants of fibroadenomas. To our knowledge, there is no review in which imaging findings of all fibroadenoma variants are presented together.
纤维腺瘤是女性最常见的良性乳腺病变。激素活动，特别是雌激素活性的增加，在纤维腺瘤的发病机制中起着重要作用。它们通常是偶然发现的。大多数纤维腺瘤具有相似的影像学表现，这些病变可被定义为单纯性纤维腺瘤（SFAs）。然而，由于组织病理学特征和成分的不同，纤维腺瘤的变体已经被描述。这些变体包括：幼年型、巨型、复杂型、黏液样、细胞型和玻璃样变纤维腺瘤。这些变体的诊断很重要。它们具有不同的临床行为、恶性转化的潜力和治疗策略。我们呈现了 SFAs 和其他纤维腺瘤变体的影像学表现。据我们所知，目前还没有一篇综述将所有纤维腺瘤变体的影像学表现汇总在一起。
