Breast Cyst Hydatid: A Case Report

Hydatid disease (HD) can arise in any part of the body. Breast involvement with HD is extremely rare; it can be isolated or secondary to disseminated hydatidosis. In this study, we present a 45-year-old female with HD located in the right breast without pulmonary or hepatic involvement. Ultrasonography revealed a multiloculated cystic mass; mammography showed a homogeneous, dense, well-circumscribed lesion and magnetic resonance image showed a peripheral rim enhanced cystic mass with internal septa located in the upper outer quadrant of the breast. Pre-operative cyst hydatid IgG (1/100) was positive. So the preliminary diagnosis of HD was made and it was completely removed surgically. The preliminary diagnosis was confirmed on histopathological examination of the specimen. HD should be kept in mind in the differential diagnosis of breast cysts. Performance of preoperative cytological examination is not necessary for all patients. Complete excision should be the first-line option for breast HD.
