Hydatid cyst in the breast is rare. We report a case of hydatid cyst in the breast in a 30-year-old Indian rural woman who presented with a lump in her left breast. MRI findings showed a cystic lesion in the breast. Histopathological examination showed features consistent with hydatid cyst with surrounding adherent pericystic breast tissue showing fibrocollagenisation and inflammatory response. ELISA for echinococcal antigen was also found to be positive. This case emphasises that preoperative diagnosis of hydatid cyst in the breast is difficult and often missed as the breast is a rare site of echinococcal infection and clinical and imaging findings are wide and non-specific. Cytological diagnosis by fine-needle aspiration may not always be possible. Therefore, hydatid cyst in the breast should always be considered in the differential diagnosis of a breast lump and histopathological confirmation is necessary for early and appropriate treatment.
乳腺包虫囊肿较为罕见。我们报告一例30岁印度农村女性乳腺包虫囊肿病例，该患者左乳出现肿块。磁共振成像（MRI）检查结果显示乳腺有一个囊性病变。组织病理学检查显示其特征符合包虫囊肿，周围粘连的乳腺囊壁组织呈现纤维胶原化和炎症反应。酶联免疫吸附测定（ELISA）检测棘球蚴抗原也呈阳性。该病例强调，乳腺包虫囊肿术前诊断困难，常被漏诊，因为乳腺是棘球蚴感染的罕见部位，临床和影像学表现广泛且不具特异性。细针穿刺进行细胞学诊断并非总是可行。因此，在乳腺肿块的鉴别诊断中应始终考虑乳腺包虫囊肿，组织病理学确诊对于早期恰当治疗很有必要。
