Hydatid cyst (cystic echinococcosis) is a chronic parasitic infection by the larval stage of the cestode that is called resulting in the development of cystic lesions in animals and humans. In this report, we describe a rare phenotype of hydatid cyst in the breast of a 23-year-old female presented with breast mass in the left upper outer quadrant for 3 months with palpable left axillary lymph nodes. Both US and mammography provided a picture of complex suspicious cystosolid lesion with amorphous micro-calcification (BIRAD-4A). Surgical consultation was performed and Tru-Cut biopsy was recommended. Histopathology results revealed multiple viable protoscolices of and suggested the final diagnosis of breast hydatid cyst. The patient returned with ruptured and infected hydatid cyst of the breast and started treatment with Albendazole 400 mg twice daily in addition to antibiotics. Following-up after two months of Albendazole treatment showed a dramatic shrinkage in the size of the cystic lesion. In conclusion, hydatid cyst should be considered as a differential diagnosis of any cystic or cystosolid lesion in the breast and any organ in the body from head to toe apart from the hair and nails. Radiologists should be aware to the benign lesions that may mimic breast cancer to avoid misdiagnosis and unnecessary invasive procedures and consequent complications.
包虫囊肿（囊型棘球蚴病）是由一种绦虫的幼虫阶段引起的慢性寄生虫感染，可在动物和人类体内导致囊性病变的形成。在本报告中，我们描述了一名23岁女性乳房包虫囊肿的罕见表型，该患者左上外象限乳房肿块3个月，可触及左侧腋窝淋巴结。超声和乳腺钼靶检查均显示为伴有无定形微钙化的复杂可疑囊实性病变（BIRAD-4A）。进行了外科会诊并建议进行粗针活检。组织病理学结果显示多个活的原头节，并提示最终诊断为乳房包虫囊肿。患者因乳房包虫囊肿破裂并感染复诊，除使用抗生素外，开始每天两次服用400毫克阿苯达唑进行治疗。阿苯达唑治疗两个月后的随访显示囊性病变大小显著缩小。总之，对于乳房及身体从头到脚除毛发和指甲外的任何器官的任何囊性或囊实性病变，均应考虑包虫囊肿作为鉴别诊断。放射科医生应注意可能模仿乳腺癌的良性病变，以避免误诊和不必要的侵入性操作及随之而来的并发症。
