title: Hydatid cyst: an unusual solid breast mass.
abstract: Breast involvement of the hydatid cyst is very rare, and it accounts for 0.27% of all cases. Cases reported in the literature are generally about various cystic and calcified forms, but the solid form of hydatid cyst in the breast is quite rare. It is difficult to differentiate the breast's malignant and benign lesions from this form of hydatid cyst by imaging methods. Therefore, we aimed to present the mammographical and sonographic findings of a 50-year-old woman patient consulted to our mammography unit of whom we determined a Breast Imaging-Reporting and Data System class 4 solid lesion in the right breast and come out as hydatid cyst pathologically.
